[Tutor] Java style assignments in Python

[Zak Arntson]

First up, don't do this:

>>> list_A, list_B, list_C = [[]] * 3

Because you'll get three variables referencing the same list.

It's not pretty, but you can do this:

>>> list_A, list_B, list_C = [[] for i in range(3)]

This creates a unique empty list for each variable. Of course, you'll have
to change the range parameter depending on how many variables you're
assigning.

My question for you is: Why do you want to do this? What kind of problem
are you programming for?
