ust have left that part out.
Anyway, I think you're doing two things wrong:
1. You aren't capturing the user's input. The input() function returns
the user's input, but you aren't assigning this to a variable; it's just
being thrown away. You should call input() li
a function that waits for the user to press a key and
then returns the key that was pressed?
Or are you asking for a function that detects whether a key has been
pressed at all?
