 Password Generator
Exercise 16 (and Solution)

Write a password generator in Python. Be creative with how you generate passwords -
strong passwords have a mix of lowercase letters, uppercase letters, numbers, and symbols.
The passwords should be random, generating a new password every time the user asks
for a new password. Include your run-time code in a main method.

Extra:

    Ask the user how strong they want their password to be. For weak passwords, pick a word or two from a list.

Discussion

There are no new topics this week, but you will need to use Python’s random module, described in this post.
