Did you paste the >>> and ... or were they printed by the interpreter?
Examples often show the entire contents of a session in the
interpreter, including the >>> and ... prompts. When you enter the
example yourself you should not include them. Also "Please enter an
integer: " is output from the program and "42" is user input to the
program, you should not paste either of them.

Where did the 12 come from? It looks like interpreter output but there
is nothing preceding it that would print a 12.
