Python Python Collections (2016, retired 2019) Dungeon Game random.sample

random.sample()

Hi everyone, I'm working on this Challenge Question that goes like this (it's from the dungeon game): I haven't shown you how to use this function yet but I'm sure you can use it. In the random library, there's a function named sample that takes two arguments: an iterable to sample from, and an integer of how many unique samples to return. Finish the get_locations function so that it returns 3 unique values from the cells argument. I don't quite understand this question. So, what I did was to look at the documentation of random.sample(), but still, I'm not sure how this relates to the Challenge Question.

sample.py 
import random


def get_locations(cells):
#    pass
    return x, y, z

Nice! It's tough to decide how much to share.

Great job figuring it out!

The pass part of the function is what threw me off. It felt a little like a trick question, to be honest. Glad to be through it!

Remember that you can return tuples in Python.

So all you need to do is set (x, y, z) to the output of random.sample(arg1, arg2).

arg1 and arg2 are listed as part of the question.

Actually in Conrado Landicho's he is returning a tuple.
