python - Get a random sample with replacement

Question

I have this list:

colors = ["R", "G", "B", "Y"]

and I want to get 4 random letters from it, but including repetition.

Running this will only give me 4 unique letters, but never any repeating letters:

print(random.sample(colors,4))

How do I get a list of 4 colors, with repeating letters possible?

Answer 1

In Python 3.6, the new random.choices() function will address the problem directly:

>>> from random import choices
>>> colors = ["R", "G", "B", "Y"]
>>> choices(colors, k=4)
['G', 'R', 'G', 'Y']
