What's the best way to generate random strings of a specific length in Python?

Question

For a project, I need a method of creating thousands of random strings while keeping collisions low. I'm looking for them to be only 12 characters long and uppercase only. Any suggestions?

CODE:

from random import choice
from string import ascii_uppercase

print(''.join(choice(ascii_uppercase) for i in range(12)))

EDIT:

If you need only digits, use the digits constant instead of the ascii_uppercase one from the string module.
