Correct. There's a module pprint which provides a function
pprint.pprint. It's like you can do this:
>>> import math
>>> math.sin(3.14/2)
0.9999996829318346

Or this:
>>> from math import sin
>>> sin(3.14/2)
0.9999996829318346

It's just that in this case, "math" and "sin" are both "pprint".

>>> import pprint
>>> help(pprint)

Kinda. Try this:

>>> dir()

There'll be some in there that you didn't make, but that's a start.
You could also try vars() or globals(), which will give you their
values as well.
