Python Code to Generate a Random Password

A good password is long and random. In Python you can generate one with the secrets module, which is made for passwords and tokens.

Python function to generate a password

import secrets
import string

def generate_password(length=12):
    chars = string.ascii_letters + string.digits + "!@#$%"
    return "".join(secrets.choice(chars) for _ in range(length))

print(generate_password())
print(generate_password(16))

Sample output (the password is random, so yours will be different):

How it works

• string.ascii_letters has all upper and lower case letters, and string.digits has 0 to 9.
• secrets.choice() picks one random character from the text.
• The generator expression picks length characters, and "".join() joins them into a string.
