It works for me, running it from file.  It fails with "invalid
syntax" (pointing to the end of *print*) if I cut and paste
the program exactly into a Python shell, presumably because the
shell gets unhappy about having more command input when it
wants to be executing the while loop.  Does this match what
you see?
