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




                      Using Escape Sequences with Strings

                 Escape sequences or characters are used to represent special characters that cannot be directly
                 inserted into a string.
                 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 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.

                      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:

                   Positive Indexing: Index from left starts with 0.
                   Negative Indexing: Index from right starts with -1. Syntax for traversing a string:

                     <name of the string> [index]
