How to randomly select an item from a list?

Question

Assume I have the following list:

foo = [\'a\', \'b\', \'c\', \'d\', \'e\']

What is the simplest way to retrieve an item at random from thi

Answer 1

Use random.choice()

import random

foo = ['a', 'b', 'c', 'd', 'e']
print(random.choice(foo))

For cryptographically secure random choices (e.g. for generating a passphrase from a wordlist) use secrets.choice()

import secrets

foo = ['battery', 'correct', 'horse', 'staple']
print(secrets.choice(foo))

secrets is new in Python 3.6, on older versions of Python you can use the random.SystemRandom class:

import random

secure_random = random.SystemRandom()
print(secure_random.choice(foo))
