    STRING

                     A sequence  of characters  which is  enclosed  or surrounded  by  single  (' '), double  (" "), or Triple
                     ('''  ''') quotes is known as a string. The sequence may include a letter, number, special characters or
                     a backslash. Python treats single quotes as double quotes.
                     Example of a string:

                      Program 3: To print a string

                          Program3.py

                       File  Edit   Format    Run    Options   Window     Help          Output
                       str = "This is Shweta's pen."                                 This is Shweta's pen.
                       print(str)

                          Creating a Single-line String
                     Single-line  string can be  created  by  enclosing  characters  inside  single  or double  quotes.  It is  like
                     assigning a value to a variable.

                      Program 4: To create a single-line string

                          Program4.py
                       File  Edit   Format    Run    Options   Window     Help

                       first_name = 'Aadya'
                       print (first_name)
                       last_name = 'Kaushal'                                            Output
                       print (last_name)
                                                                                     Aadya
                       str = ' '
                       print (str)                                                   Kaushal

                          Creating Multiline String

                     A multiline string in Python begins and ends with either three single quotes or three double quotes.
                     Any quotes, tabs, or newlines in between the “triple quotes” are considered part of the string.
                      Program 5: To create a string.

                         Program5.py

                      File  Edit  Format   Run   Options   Window     Help

                      print('''A sequence of
                      characters are called a string.
                      Strings are used by programming
                      languages to manipulate text such
                      as words and sentences.''')

                                                                                          Functions and String in Python  157
