In python:

4. A website requires that users create a password that meets the following requirements: The password must be at least eight characters long. It must contain at least one uppercase letter. It must contain at least one lowercase letter. It must contain at least one numeric digit. It must contain at least one symbol from the list: &, *, %, $, #, !, ? Write a function valid_password that takes a password as a string, and returns True (the Boolean value!) if the password passes all the requirements for the website, and False otherwise. For example, valid_password ('8#Z#Qb5qL3') should return True , and valid_password ('Password1') should return False . You may find the string methods islower(), isupper(), and isdigit() to be helpful. See the python string methods docs for more info
