Why "hand = hands.Hand(size=5, die_class=dice.D6)" rather than "hand = Hand(size=5, die_class=dice.D6)" in the console?

I don't understand why hands.Hand() part. Why do we need to call the name of the file with an attribute of Hand(size=5, die_class=dice.D6)?

You didn't provide a link to a course page, but I'd guess that "hands" was imported as a module and the class "Hand" wasn't specifically imported:

import hands            # with this you must call hands.Hand()
#----------------------------- OR ----------------------------
from hands import Hand  # with this you can simply call Hand()

Sorry, it's from this lesson: https://teamtreehouse.com/library/giving-a-hand

And the issue I'm referring to happens at 2:15.

I guessed it! At 2:08 he says "And let's import dice, and let's import hands.". He does that with this code:

import dice, hands

So those imports give you access to the files, but not directly to the classes within them. You still need to name the module to get to the class. And that explains "hands.Hand()".

If he had done the other kind of import, then "Hand()" could be used.
