I'm back with another simple question.
I won't dwell over this like I did the last one. I'd just like to know why the author of the book I've been reading says
Gives the result
5 5
He has a few different examples all to do with the printTwice call but when I try and do it, it says
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
NameError: name 'printTwice' is not defined
Thanks.
