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