1# Basic syntax:
2import random
3random.sample(your_set, number_of_elements)
4# Where:
5#	- number_of_elements is the number of elements you want to sample
6# 		without replacement from your_set
7# Note, the samples elements are returned as a list. Use set(the_list)
8#	to convert back to a set
9
10# Example usage:
11your_set = {'a', 'bunch', 'of', 'unique', 'words'}
12random.sample(your_set, 1)
13--> ['words']
14
15random.sample(your_set, 3)
16--> ['words', 'of', 'a']
