Problem
How do I retrieve an item at random from the following list?
foo = ['a', 'b', 'c', 'd', 'e']
Solution
Use
For cryptographically secure random choices (e.g., for generating a passphrase from a wordlist), 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))Code Snippets
