How to Change the Column Name in a DataFrame

DataFrame is a data structure which stores tabular data in a table-like format. It is primarily used for storing and processing structured and unstructured data.

A DataFrame consists of two types of columns: Indexes and columns.

Indexes are used to organize rows into groups that can be addressed by the same column name, whereas columns are used to store values within a particular row.

The following code snippet changes the column name from “Date” to “Month” in the DataFrame created in the previous section:

Columns = pd . DataFrame (

data = my_data ,

index = my_index ) . rename ( columns = { ‘Date’ : ‘Month’ }, axis = 1 )
