python randomly sample entry from a set
# Basic syntax:
import random
random.sample(your_set, number_of_elements)
# Where:
# - number_of_elements is the number of elements you want to sample
# without replacement from your_set
# Note, the samples elements are returned as a list. Use set(the_list)
# to convert back to a set
# Example usage:
your_set = {'a', 'bunch', 'of', 'unique', 'words'}
random.sample(your_set, 1)
--> ['words']
random.sample(your_set, 3)
--> ['words', 'of', 'a']
