Fix Python – How do I pick 2 random items from a Python set? [duplicate]

Question

I currently have a Python set of n size where n >= 0. Is there a quick 1 or 2 lines Python solution to do it? For example, the set will look like:

fruits = set(['apple', 'orange', 'watermelon', 'grape'])

The goal is to pick 2 random items from the above and it’s possible that the above set can contain 0, 1 or more items. The only way I can think of doing the above is to convert the set to a list(mutable) from where I can access 2 random unique index within the length of the set.

Now we will see solution for issue: How do I pick 2 random items from a Python set? [duplicate]

Answer

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).
