                      Recap


                         The statements that are used to repeat a set of instructions are called iterative or looping
                         statements.
                          Python provides two types of looping statements— for and while.
                          The for statement executes a simple or compound statement for a fixed number of times.
                          The range( ) function is an in-built function of Python.
