How to return a list of 4 strings, each random, from the given string characters = 'ygobpr'?

Answer 1

You can create a list of random characters as following:

import random
def create_code(characters):
    return list(random.choice(characters) for n in xrange(4))

if __name__ == '__main__':
    characters = 'ygobpr'
    print create_code(characters)

Answer 2

each string should just be one letter out of the string 'ygobpr' –

You can just use random.sample() directly:

In [8]: random.sample(characters, 4)
Out[8]: ['y', 'b', 'o', 'p']
