    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 7: To join two or more strings using string concatenation operator

                         Program7.py                                               Output
                      File  Edit  Format   Run   Options  Window    Help        HereIsPython

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

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

                     Program 8: To repeat a string using string replication operator

                         Program8.py                                               Output

                      File  Edit  Format   Run   Options  Window    Help        HelloHelloHello
                      s1 = 'Hello'
                      s = s1 * 3
                      print(s)

                                                                                                             PURE
                         There are  around  700  separate  programming  languages.  Some  of  the  most
                         popular ones are JavaScript, Swift, Scala, Python, PHP, Go, Rust, Ruby and C#.      FACT

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

                        upper(): The upper() function converts all lowercase letters to uppercase. The syntax of using
                        the upper() function is:
                         string_name.upper()

                                                                                          Functions and String in Python  97
