               In a Python program, indentation is of crucial importance. Make sure that all statements in a suite are indented at
               the same level. Usually four spaces are used to write the code at next level of indentation.

                 1.  Identify the type of control flow for the following:
                   a.  The set of statements are executed repeatedly.
                   b.  The statements are executed in the same order as they are given in the program.
                   c.  A set of statements will be executed if the given condition is True.
                 2.  Name the following:
                   a.  A dummy statement that is ignored by the interpreter.
                   b.  A type of statement that has a header clause followed by a suite.
                   c.  The character that ends a header clause.
