Python Script to generate a random password given the length. Copies to clipboard (at least on MacOS). To generate a 20 length password: `py random-secret.py 20`.

random-secret.py

import random
import string
import subprocess
import sys

length = int(sys.argv[1])

def write_to_clipboard(output):
  process = subprocess.Popen('pbcopy', env={'LANG': 'en_US.UTF-8'}, stdin=subprocess.PIPE)
  process.communicate(output.encode('utf-8'))

def random_char():
  p = random.randint(0, 100)
  if p < 5:
    char = ' '
  elif p < 15:
    char = random.choice(string.punctuation)
  elif p < 65:
    char = random.choice(string.ascii_letters)
  else:
    char = random.choice(string.digits)

  return char

secret = ''
for i in range(0, length):
  secret += random_char()

write_to_clipboard(secret)
print(f'Secret {secret} generated and copied to clipboard.')
