Password Generator

Created on Jan. 21, 2017 by Julien Palard

Build a password generator by writing a function named pwgen taking the following parameters:

  • length: the length of the generated password
  • with_digits: Defaulting to True, to allow or disallow digits
  • with_uppercase: Defaulting to True, to allow or disallow capital letters

pwgen returns a password with lowercase letters AND digits if with_digits == True AND uppercase letters if with_uppercase == True.

When asked for a password with multiple character categories, all categories have to be represented. For instance, with with_digits == True, the password must have at least one lowercase letter AND at least one digit.

Hints

  • Expect Moulienette to call the function many times, so avoid using blocking calls to obtain "truly random bits", it will just exhaust our system entropy and will take forever to check your exercise.
  • There's no corrections yet, hit the `Submit` button to send your code to the correction bot.
  • Keyboard shortcuts:
    • Ctrl-Enter: Send your code to the correction bot.
    • Escape: Get back to the instructions tab.
