    USING ESCAPE SEQUENCES WITH STRINGS

                      Escape sequences or characters are used to insert special characters that are not directly printable
                      or representable in a string in Python. They represent non-printable or special characters within
                      strings. Quotes are special characters  and to insert them in a string we must escape them with a
                      \ character in front of them.

                      An escape sequence is a sequence of characters that does not represent itself when used inside a
                      character or string. It is typically used to specify actions such as special characters and formatting
                      actions. For example, carriage returns and tab movements. The backslash (\) is a special character
                      and is also known as the escape character in Python. For example, '\t' for tab, '\n' for new line and

                      '\r' is for carriage return.
                      Program 5: To print special symbols using escape sequences

                          Program5.py
                       File  Edit  Format   Run   Options  Window    Help

                       print('I love programming in \n Python')

                      You will get the following output:

                          Output
                       I love programming in
                        Python

                      TRAVERSING A STRING

                      Traversing means visiting each element and processing it as required by the program. We can
                      access the characters of a string one at a time using indexing.
                      There are two ways of indexing a string:

                         Positive Indexing: Indexing starts from the left, with the first character at index 0.
                         Negative Indexing: Indexing starts from the right, with the last character at index -1.
                      Syntax for traversing a string:

                          <name of the string> [index]
                      Program 6: To access different elements of a string

                          Program6.py                                               Output
                       File  Edit  Format   Run   Options  Window    Help         o
                                                                                  e
                       name = 'orange'
                       print(name[0])
                       print(name[-1])
