Here is a Python program to give comments in Python

import re

def add_comment(s):
    """
    :param string s: string to be commented
    :return: commented string
    :rtype: str
    """
    return "# " + s

# Enter the string
string = "This is a string"

# Calling the function
print((add_comment(string)))

#Example Output
# # This is a string

#Remember to inspect code for bugs.
