Oh, I found the error. You have
                  You can look at my program here                      placed an extra quote. I will explain
                  and tell me. I am not very good in                     you how and when to use single
                  writing code on Strings in Python.                     and double quotes with Strings.

                 A function is a block of organised and reusable code used to perform a single or related action. Functions
                 receive data in the form of arguments and use it to run a specified set of statements and produce the
                 final output.


                 FEATURES OF FUNCTION

                 Some important features of functions are:

                     A program is divided into small modules, and each module performs a specific task. Each module
                    can be called as per the requirement.

                     We can call a function as many times as required. This saves the programmer's time and effort to
                    rewrite the same code again. Therefore, it also reduces the length of the program.
                     Dividing a bigger program into smaller functions makes the program more manageable. It makes
                    debugging easy and makes the code efficient, both in terms of time and memory usage.
