In python, if we want to work with CSV files we have to import CSV module

CSV Write: 

import csv

file = open("sample.csv", "w", newline = "")    # First we have to open the file

csvwrite = csv.writer(file)     # Creating the object

csvwrite.writerow(["Name", "Age", "Occupation"]) # Write row method will take only one argument

csvwrite.writerow(["Alex", "25", "Worker"]) # We have to separate the values with comma

Output:

CSV Read:

import csv

file = open("sample.csv", "r")

csvread = csvreader(file)

for column in csvread:

    print(column)

Output:

['Name', 'Age', 'Occupation']

['Alex', '25', 'Worker']
