A hash sign (#) that is not inside a string literal begins a comment. All characters after the # and up to the end of the physical line are part of the comment and the Python interpreter ignores them.
#!/usr/bin/python # First comment print "Hello, Python!" # second comment
This produces the following result −
You can type a comment on the same line after a statement or expression −
name = "Madisetti" # This is again comment
You can comment multiple lines as follows −
# This is a comment. # This is a comment, too. # This is a comment, too. # I said that already.
Following triple-quoted string is also ignored by Python interpreter and can be used as a multiline comments −
''' This is a multiline comment. '''
