Function blocks begin with the keyword def followed by the function name and parentheses
                      ( ( ) ).

                       Any input parameters or arguments should be placed within these parentheses. You can also
                      define parameters inside these parentheses.
                       The first statement of a function can be an optional statement—the documentation string of
                      the function or docstring.
                      The code block within every function starts with a colon (:) and is indented.

                  Syntax:
                  def function_name(parameters):
                      statement(s)

                  On running the program, we get the following output:

                         The if statement is the simplest conditional statement.
                         The  if…elif…else ladder  helps us to  test  multiple conditions and  follows a  top-down
                       approach.
                         Looping statements are very useful and necessary for developing applications.
                         Python provides two types of looping statements—for and while.
                         The break is a keyword in Python which is used for bringing the program control out of
                       the loop.
                         When a continue statement is encountered inside a loop, control of the program jumps
                       to the beginning of the loop for next iteration, skipping the execution of rest of the
                       statements of the loop.
                         A function is a block of organized and reusable code used to perform a single or related
                       action.
