Steps to Install pandas python on Windows or Mac OS X Machine
There are a few steps to installing pandas python on your Windows or Mac OS X Machine. The installation is not difficult but it does require some patience and knowledge of the computer’s directory.
1) Download the latest version of pandas for your operating system from this link: https://pandas.pydata.org/#installing
2) After downloading the file, you will need to extract it using a program like WinRAR or 7-Zip (a free download).
3) Once you have extracted it, open up the folder and copy all files from within into C:\Python36\lib\site-packages
4) Open up Command Prompt (Windows) or Terminal (Mac OS X).
5) Type in pand
Pandas and Data Frame Operations – Select Column, Reindex, Aggregate, Resample, Reshape DataFrame, Split Rows or Columns at a Specified Value
Pandas data frames are an efficient and simple way to organize data. They can be created from scratch (linearly) or from a list of tuples, a dictionary, or a numpy array. Data frame operations allow for quick and easy changes to be made. Selecting columns with the .ix indexer, reshaping the dataframe with .reshape(), aggregating values in different ways with the .agg() method, and splitting rows into new columns can all be done in an instant.
Pandas is Python’s core package for data analysis that provides features such as cleanly displaying tables of time series data, calculating descriptive statistics (including standard deviation), resampling datasets (including cross-validation), running linear regression and many more.
Replace Values in a DataFrame with Duplicate Records using Fillna() Method
The Fillna() function in pandas allow you to overwrite a given value with a different value for the specified column.
