Python Projects For Beginners – 1. Variables and Maths

Introducing the print function

Before you start coding, let me remind you quickly of the print function. Simply put, it’s used to print whatever you pass into its parentheses. Example: print ('Hello World') will simply print Hello World, and print ( 1 + 2 ) will print 3 as Python is intelligent enough to perform Maths. However, print ( '1 + 2') will print 1 + 3 (without doing the addition because it considers the numbers as strings in this case) and I let you try what print ( '1' + '2') will show!

Introducing Variables

In Python, a variable is a named container that contains some value and stores it in the computer memory. The value can be of any data type: string, integer, float, … The stored value can then be retrieved by calling the variable name. Examples: x = 2 will assign the value 2 to the variable x, y = 'hello' will store the text hello inside the variable called y and Pi = 3.14 will assign the value 3.14 to the variable named Pi.

Learn the hard way

Now that you’re familiar enough with the 2 above mentioned concepts, let’s use them to code some useful Python program.

Imagine you’re working in a transportation company, and you’re boss asked you to prepare a status report. This should include the total number of buses, space in each bus, number of drivers, the number of passengers, buses that are not used, buses used, the total buses capacity, and the average passengers per bus.

buses = 100
space_in_a_bus = 20.0
drivers = 30
passengers = 130
buses_not_driven = to be calculated
buses_driven = to be calculated
total_capacity = to be calculated
average_passengers_per_bus = to be calculated

You’re going to use the given numeric data and do some maths on it to get the requested numbers, then print the results. use the guided code file below to code this project:

# 1. Declare and initiate all the variables for this project
        # Use the given variable names and values to do so, if the variable has no value, then you need to do some math to calculate it's vale, E.G. average_passengers_per_bus = passengers / buses_driven

Python Projects For Beginners – 2. More Variables and the Print Function

Introducing Strings

In the previous exercise, we’ve used strings. Simply put, a string is a text, something readable by humans, whatever you put between quote marks for the print function is considered a string, e.g. print ('The Number of buses used is'). In this exercise, we’ll use more variables, strings and we’ll print them out.

Embed variables inside a string

You embed variables inside a string by using specialized format sequences and then putting the variables at the end with a special syntax, for example, print ("We have", passengers, "to buspool today."). This statement will embed the variable passengers inside the string passed to the print function.

Learn the hard way

The purpose of this exercise is to let Python talks about your friend, using his/her information, such as age, height, weight, hair color, eyes color and create a small descriptive paragraph about your friend.

Your_friend_name = 'name here'
Your_friend_age = age here
Your_friend_height = height here
Your_friend_weight = weight here
Your_friend_eyes = 'eyes color here'
Your_friend_teeth = 'teeth color here'
Your_friend_hair = 'hair color here'

After inserting your friend’s information to the code below, you need to let Python build a small descriptive paragraph about your friend. The output should be:

Let's talk about (your friend's name'
He's 'your friend height' inches tall.
He's 'your friend weight' pounds heavy.
Actually, that's not too heavy.
He's got 'your friend eyes color' eyes and 'your friend hair color' hair.
His teeth are usually 'your friend teeth color' depending on the coffee.
If I add 'age' , height, and 'weight' I get 'addition result'.

Use the below-guided code file to code on your computer, the result should be the same.

# 1. Declare and initiate your friend's information usig the above mentioned variable names  
# your code goes here; remove this comment
# your code goes here; remove this comment
# your code goes here; remove this comment
# your code goes here; remove this comment
# your code goes here; remove this comment

# 2. Print the descriptive paragraph text and insert the variables into it e.g. print ("He's %d inches tall." % Your_friend_height)
# your code goes here; remove this comment
# your code goes here; remove this comment
# your code goes here; remove this comment
# your code goes here; remove this comment
# your code goes here; remove this comment

# 3. Save and run your code to see the result

If you get the same result as the above picture, then congratulations, you did it, now you can move to the next project. Otherwise please try again before moving forward. If you need help, please feel free to ask your questions in the comment section.

Python Projects For Beginners – 3. Strings and Text

This Python exercise is a bit similar to the previous one. Its purpose is to let you use more Python strings and built-in functions to produce meaningful text. This exercise is a bit hard, so please, carefully follow the below guidelines to code. If you get stuck try again until you get it done.

Introducing The %d, %s and %r Tokens

The new concepts here are the Boolean values of True or False that will be used. Also, we’ll be using %d, %r and %s tokens.

Simply put%s token allows inserting (and potentially format) a string. The %s token is replaced by whatever I pass to the string after the % symbol.

The %d is a integer decimal representation of a numeric object. (It will raise TypeError for non-numeric objects).

The %r is the Python “representation” for the object, a string which, if presented to a Python interpreter should be parsed as a literal or as an instantiation of a new object of that time and with the same value.

Learn The Hard Way

Write a Python Program that will print out the following paragraph:

There are 2 types of people.
Those who know binary and those who don't.
I said: 'There are 2 types of people.'.
I also said: 'Those who know binary and those who don't.'.
Isn't that joke so funny?! False
This is the left side of…a string with a right side.

Start by declaring and initializing the following variables:

x = "There are ** types of people." * *
binary = "binary"
do_not = "don't"
y = "Those who know ** and those who **." * (binary, do_not)

N.B. You should replace the asterix (*) characters with the above-presented tokens. The print these 2 variables, each one in a separate line.

Now, reuse the above variables and insert them in the print function to repeat what’s been said.

print "I said: **." * x
print "I also said: '**'." * y

Next, define a new variable named hilarious and assign the Boolean value False to it. Then reuse the assigned value in another variable named joke_evaluation that contains the text “Isn’t that joke so funny?!” (False should follow this question) joke_evaluation = "Isn't that joke so funny?! %r"

Finally, print the question and the answer False following it.

If you get the same result as the above picture, then congratulations, you did it, now you can move to the next project. Otherwise please try again before moving forward. If you need help, please feel free to ask your questions in the comment section.

Python Projects For Beginners – 4. Prompting User

The purpose of this exercise is to let you get some values from the user and manipulate them to produce a small paragraph.

Introducing The Python input Function

if the Python print function lets you print whatever value you passed to it in its parentheses, then the input function lets you obtain data you want by asking the user to type it into your Python program. For example: input("what is your name?") will show this question and halts to get it an answer from you (the user).

Using values obtained from The Python input Function

To get the most out of this function, it’s useful to assign the obtained value to a variable that you can call and manipulate later on. For example: name = input ('what is your name?') will assign the entered value to the variable named ‘name’ which you can use later on.

Learn the Hard Way

The purpose of this exercise is to let Python ask you about your information: age, height and weight. Then reuse those to display a small descriptive paragraph about you.

The output of this program should be: So, you're '30' old, '158' tall and '60' heavy.

Use the below-guided code file to write the program, if you want to code on your computer that’s fine, the result should be the same.

# 1. Declare and initiate the variables age, height, weight, then let Python ask you to enter them using a question inside the input function e.g. age = input("How old are you? ")

#Your code goes here, delete this line
#Your code goes here, delete this line
#Your code goes here, delete this line

# 2. Reuse the above-obtained value to produce the paragraph, remember the %r token 

#Your code goes here, delete this line

Python Projects For Beginners – 5. Reading and Writing Files

Introducing Python File Methods

Python includes all sort of handy functions, methods, libraries and more. In this part, we’re interested in file modes and functions. we’ll be using them in our code. Just remember the followings:

• close: Closes the file. Like File- >Save.. in your editor.
• read: Reads the contents of the file. You can assign the result to a variable.
• readline: Reads just one line of a text file.
• truncate: Empties the file. Watch out if you care about the file.
• write(stuff): Writes stuff to the file.
• seek: Sets the file’s current position at the offset

The purpose of this program is to let you open a file and manipulate it with Python.

Lear The Hard Way!

1. Start a new Python script by initializing a variable with a concatenated string containing newline characters
   poem = 'I never saw a man who looked\n'
poem += 'With such a wistful eye\n'
poem += 'Upon that little tent of blue\n'
poem += 'Which prisoners call the sky\n'
2. Next, add a statement to create a file object for a new text file named “poem.txt” to write content into
   file = open( 'poem.txt' , 'w' )
3. Now, add statements to write the string contained in the variable into the text file, then close that file
   file.write( poem )
file.close()
4. Then, add a statement to create a file object for the existing text file “poem.txt” to read from
file = open( 'poem.txt' , 'r' )
5. Now, add statements to display the contents of the text file, then close that file
for line in file :
print( line , end = '' )
file.close()
6. Save the file in your scripts directory, then open a Command Prompt window there and run this program to see the file get created then read out to display
7. Launch the Notepad text editor to confirm the new text file exists and reveal its contents written by the program
8. Now, add statements at the end of the program to append a citation to the text file then save the script file again
   file = open( 'poem.txt' , 'a' )
file.write( '(Oscar Wilde)' )
file.close()
9. Run this program again to re-write the text file then view its contents in Notepad to see the citation now appended after the original text content

If you get the same result as the above picture, then congratulations, you did it, now you can move to the next project. Otherwise please try again before moving forward. If you need help, please feel free to ask your questions in the comment section.

Python Projects For Beginners – 6. Functions and Variables

Defining a Python Function

If you remember from the previous article about the Range Function, we’ve used a schema to represent it. We said that a function can be presented as a sort of a system that accepts some input, perform operations on them, and then return some outputs.

In Python, functions do three things:

1. They name code blocks the same way that variables names strings and numbers.
2. They take inputs, those are called arguments.
3. Using the 2 above properties, they let you create your own code snippets than you can use as long as you need inside your programs.

Example:

def my_function (books_count, notebooks_count)

print ("You have %d books!" %books_count)
print ("You have %d notebooks!" %notebooks_count)
print ("Man that's enough to study!")
print ("Get to work.\n")

Let’s explain quickly what these lines mean, first we define the function “my_function” and we give it the arguments books_count and notebooks_count.

Then in the following lines, we tell the function what to do with those arguments. Simply put, it will embed them in the strings and print the result. Note the indentation of print statements inside the function, any line that is indented is a part of the function.

Python Functions: Learn the hard way!

Use the above function to print a paragraph about functions and how to use them. Follow the guided code below.

The final text to be printed should be:

We can just give the function numbers directly:
You have 10 books!
You have 10 notebooks!
Man that’s enough to study!
Get to work.
OR, we can use variables from our script:
You have 12 books!
You have 13 notebooks!
Man that’s enough to study!
Get to work.
We can even do math inside too:
You have 17 books!
You have 15 notebooks!
Man that’s enough to study!
Get to work.
And we can combine the two, variables and math:
You have 35 books!
You have 30 notebooks!

# To make the work easy for you, the function is already here
def my_function(books_count, notebooks_count):
  print ("You have %d books!" %books_count)
  print ("You have %d notebooks!" %notebooks_count)
  print ("Man that's enough to study!")
  print ("Get to work.\n")

  
# 2. print the sentence "We can just give the function numbers directly:" non indented, then call my_function with the arguments (10, 10)
# Your code goes here, remove this line 
# Your code goes here, remove this line

# 3. print the sentence "OR, we can use variables from our script:", then assign the values 12 and 13 to the variables amount_of_books and amount_of_notebooks succevely 
# Your code goes here, remove this line 
# Your code goes here, remove this line
# Your code goes here, remove this line 

# Call my_function with the argument amount_of_books, amount_of_notebooks
# Your code goes here, remove this line 

# 4. print the sentence "We can even do math inside too:" and call my_function with addition for it's aguments, use 10 + 7 and 13 + 2
# Your code goes here, remove this line 
# Your code goes here, remove this line 

# 5. print the sentence "And we can combine the two, variables and math:" and call my_function using the argumnts amount_of_books + 23, amount_of_notebooks + 17

If you get the same result as the above picture, then congratulations, you did it, now you can move to the next project. Otherwise please try again before moving forward. If you need help, please feel free to ask your questions in the comment section.

Oh, by the way, if you think 10 books aren’t enough to study and get to work, then you should buy some books from Amazon!

Python Projects For Beginners – 7. Functions and Files

The purpose of this exercise is to allow you dive deeper with functions and files. You’ll need to code on your computer.

Introducing the Python sys Module

First we need to import the argv function from the sys module, then we need to assign the current file name to argv[0], don’t feel overwhelmed here, as we’ll discuss this in a future article. But for now, we can do this like so:

from sys import argv
input_file = argv[0]

How to comment code in Python

Add a comment to your code at the third line, it can be any text you want. Remember that comments in Python are inserted beginning with the hash character #, e.g. # some text here will tell Python to skip this line and go to the next one.

Code it The Hard Way!

Second, define 3 functions, print_all to print the whole file content, rewind to let you view previous content of the file, and print_a_line to print a specific line of the file.

The first and second function accepts f as argument. the third one accepts line_count and f as arguments.

Third, call the open method on the input_file argument and assign it to current_file then print the sentence "First let's print all the content of this file:\n" (the \n is just a symbol used to tell Python to go to a new line)

Fourth, call print_all function and pass current_file as an argument to it, then print "Now let's rewind, like going back in a tape." and call the rewind function on the same argument, and print "Let's print the first three lines of this file:"

Fifth, define a variable called current_line and assign the value of 1 to it. Then call the function print_a_line and pass the parameters current_line, current_file to it.

Next, increase the value of current_line by 1 then pass it with current_file as arguments to the print_a_line function. (remember that to increase the value of an existing variable you simply assign its old value +1 to itself e.g x = x + 1 will increase x by 1.)

Finally, repeat the last operation once more to increase the line number and print whatever it contains.

If you get the same result as the above picture, then congratulations, you did it, now you can move to the next project. Otherwise please try again before moving forward. If you need help, please feel free to ask your questions in the comment section.

Python Projects For Beginners – 8. If Statement

We’ve recently discussed the if statement and how you can use it for branching in Python programming. Now, we’ll go the hard way directly in this section.

This exercise is fairly easy and straight forward. It’s going to compare the number of people, cars, and buses, then print a meaningful sentence based on each comparison result.

First, declare and initiate 3 variables for people, cars and buses. You can use whatever values you want or copy mine if you’d like.

Second, compare people to cars. if there are more cars than people, then print “Too many cars in the world” otherwise print “We need more cars!”

Third, compare people to buses. if you find more buses than people, then print “Bad news, the human race is about to disappear” otherwise print “The world is safe”

Fourth, increase the value of cars and compare those to people again. If people>= cars then print “there more people than buses or maybe everyone has a car.”. If people <= cars then print”there more people than cars or maybe everyone has a car.”t. And if people == cars then print “Every one has a car, that’s cool.”

#Remove the comments and start coding
#people = 20
#cars = 30
#buses = 15

# Your code goes here
# Your code goes here
# Your code goes here
# Your code goes here
# Your code goes here
# Your code goes here
# Your code goes here
# Your code goes here
# Your code goes here
# Your code goes here

If you used the same values as me and got the same result as the above picture, then congratulations. if your values are different than mine and you get the result without the interpreter throwing errors, you did it, now you can move to the next project. Otherwise, please try again before moving forward. If you need help, please feel free to ask your questions in the comment section.

Python Projects For Beginners – 9. Loops and Lists

We’ve talked about lists, tuples, sets, and dictionaries in a previous article, and we’ve discussed using the for loop as well. So in this section, we’ll be using what we’ve learned to manipulate lists using the for loop in a simple Python Beginners Exercise.

First, create 3 lists named: my_count, fruits and change. And containing [1, 2, 3, 4, 5, 6] then ['apples', 'oranges', 'banana', 'lemons'] and [1, 'cents', 2, 'half euro', 3, 'euros']

Second, use the for loop to produce a counter of the first list my_count and print the result, use print ("This is count %d" % number)

Third, use another for loop to print each element in the second list fruits. Use print ("A fruit of type: %s" % fruit)

Fourth, use another for loop to print out each element in the third list named change, you can use print ("I got %r" % i) where i is the variable for which the for loop will iterate through the list’s elements.

Fifth, declare and initiate an empty list named elements then use a for loop with range (1, 6) to add elements to the empty list. You can do that using the following code block:

for i in range(0, 6):
print ("Adding %d to the list." % i)

elements.append(i)

Finally, print the number of elements in the list using a for loop and print ("Element was: %d" % i)

Use the guided coding file below to write your code.

#my_count = [1, 2, 3, 4, 5, 6]
#fruits = ['apples', 'oranges', 'banana', 'lemons']
#change = [1, 'cents', 2, 'half euro', 3, 'euros']

# this first  for loop goes through a list
