In Python, there are 2 ways to comment your code: single-line and multiple-line comment.

Single-line comment

A single-line comment starts with the pound(#) key and is automatically terminated by the end of line. For example,

# This whole line in itself is a comment.
 
pi = 3.14159 # This is the value of pi up to 5 decimal points.

Multiple-line comment

A multiple-line comment uses triple-single-quote(''') or triple-double-quote(""") as the delimiter. It starts with the delimiter and terminates with a line containing only the delimiter. For example,

""" This is a multiple lines comment that uses triple double quote.
It should end with a line containing only triple double quote.
"""
 
pi = 3.14159
 
''' This is another comment block that uses triple single quote.
It should end with a line containing only triple single quote.
'''
