                      STRING OPERATORS

                      There are two basic string operators in Python, + and *. Python uses + for concatenation and * for
                      replication. The description of these operators areas follows:

                         String Concatenation Operator (+): String concatenation operator joins two or more strings
                        into one.

                      Program 8: To join two or more strings using the string concatenation operator.

                       s2 = 'Is'
                       s3 = 'Python'
                       s = s1 + s2 + s3                                             Output
                       print(s)                                                  HereIsPython

                         String Replication Operator (*): The replication operator is used to repeat the string for a given
                        number of times.

                      Program 9: To repeat a string using the string replication operator.

                        print(s)                                                 HelloHelloHello

                      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)
