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.
