after a glance, consider these notes:

you seem to be writing three functions for the three difficulty levels.
you shouldn't need to do that: good function design would mean you can
pass in what you need to know (like the range from which the number is
chosen - you've used 15, 20 and 50); the code is otherwise essentially
common, which indeed makes it a good candidate for a function.

but the functions you've written are really short (one-liners), and the
code that seems to belong to the functions is actually outside them...
in Python that's an indent thing: indentation tells the interpreter what
lines of code belong to a particular block, so everything that belongs
inside

def foo():

needs to be indented to be considered part of that clode block.

And then as has already been noted, the order of things matter.  Unlike
some languages, a function definition is an executable "statement"
(usually a whole block of code, see above) that is executed as it is
seen, and the result is a callable object which then can be called by
subsequent code.  So just keep that in mind.
