Use your Python skills to write three functions related to good password management.

Password Strength

Write a function to test whether a password is strong or not.

Fill in parts of the code marked TODO:

def is_strong(password):
  # TODO: If password is less than 12 characters, return False.
  symbols = ['!', '@', '#']
  # TODO: Write a For Loop to iterate through the list of symbols.
  #       If any symbol is in the password, return True.
  #       Otherwise, return False.

Hint: use the len function to get the length of a string. Review lessons on If/Elif/Else, Functions, and For Loops.

Password Timeout

Write a function that times out for 10 seconds if the user tries an incorrect password 3 times in a row.

Use global variables to store the secret password and the number of times the user has tried.

Fill in parts of the code marked TODO:

from time import sleep
secret_password = # TODO: set password here
num_tries = 0

def try_password(entered_password):
  global num_tries
  # TODO: If entered_password matches secret_password, return True.
  # TODO: Otherwise, increase num_tries by 1.
  # TODO: If num_tries is 3 or more, sleep for 10 seconds and reset num_tries to 0.
  return False

Hint: call sleep(10) to sleep for 10 seconds. Review the Variables lesson for how to increase the value of a variable, and the If/Elif/Else lesson for how to compare two numbers.

Password Lockout

Write a function that locks the user account if the user tries an incorrect password 3 times in a row.

Use global variables to store the secret password and the number of times the user has tried.

Fill in parts of the code marked TODO:

from time import sleep
secret_password = # TODO: set password here
num_tries = 0

def try_password(entered_password):
  global num_tries
  # TODO: If num_tries is 3 or more, return False.
  # TODO: If entered_password matches secret_password, reset num_tries to 0 and return True.
  # TODO: Otherwise, increase num_tries by 1 and return False.
  return False
