How to generate a random string in Python
Python is a powerful language that allows programmers to perform various tasks using built-in libraries. A random string, for example, can be generated using the built-in libraries. Two libraries are imported for this:
import string
import random
Using this random module, different random strings can be generated.
random.choice() is used to generate strings in which characters may repeat, while random.sample() is used for non-repeating characters.
