Never use assignment operator in place of equality operator in the test
                                        condition as it may cause an infinite loop.



            Program: To add first five natural numbers.














            On running the above program, you will get the following output:

                  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.
                 A sequence is a succession of values bound together by a single name.
                   The  while  statement  executes  a  set  of  statements  repeatedly,  until  the  logical  expression
                 evaluates to true.
                 To come out of the infinite loop, we can either close the program window or press Ctrl + C.

                 The else block is executed when the condition given in the while statement becomes false.
                  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.
