That depends on what you are actually testing. If you are intending to test the

Unless you decide to put help(collections) at the top
of your program because it makes the bug go away. :-)

Hello, guys
I'm using python to automate some seriously boring stuff at work, but would
like to improve current code.
The way it is now, PyAutoGui moves mouse and clicks the Application. I am,
therefore, hostage of my python "assistant", as I cannot use my computer while
the .py is running.

Is this a good way to test if random numeric output? It seems to work
under Python 2.6 and 3.6 but that doesn't make it 'good'.
### Code
import random
def my_thing():
""" Return a random number from 1-6
>>> 0 < my_thing() <=6
True
>>> 6 < my_thing()
False
"""
return random.randi

It’s a fantastic idea. I will also have a good understanding of the internals
of the standard library and at I can learn more about testing.

In Python 3, what's the difference between these two classes?
