連接字符串

您還可以相對容易地將字符串“連接”或“混入”：

  listofstrings = ['a', 'b', 'c']
  result = "**".join(listofstrings)

然後result將包含字符串：

  a**b**c

16 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.
