STRING BUILT-IN FUNCTIONS
                  Python includes the following built-in functions to manipulate strings:

                     len(): The len() function calculates and returns the length of a string supplied as an argument.
                    Syntax of using len() function is:

                    len(string_name)
                     lower(): The lower() function converts all uppercase letters to lowercase. Syntax of using lower()
                    function is:

                    string_name.lower()

                     upper(): The upper() function  converts all  lowercase  letters  to  uppercase.  Syntax  of using
                    upper() function is:
                    string_name.upper()
                     capitalize(): The capitalize() function returns a string with the first character in capital. Syntax
                    of using capitalize() function is:

                    string_name.capitalize()
