                       String Operators

                  There are two basic string operators in Python, + and *. Python uses + for concatenation and * for
                  replication.

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

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

                    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.
