Read specific columns from a CSV file in Python

Pandas consist of read_csv function which is used to read the required CSV file and usecols is used to get the required columns.

We have to make sure that python is searching for the file in the directory it is present. In order to that, we need to import a module called os. This module provides functions to interact with the Operating System.

import pandas as pd
import os

#chdir is used to change the directory.


Using the os.chdir function we can change the current working directory to the directory in which our CSV file is present.
