Password

Save all functions into the same file named password.py.

1. Write the function has_upppercase() that takes a string, and returns True if it contains any uppercase letter and False otherwise.

   See the following examples:

   >>> has_uppercase("Mypassword")
   True
   >>> has_uppercase("new#@*password657")
   False
   >>> has_uppercase("hi#@*U981")
   True
   >>> has_uppercase("05687xsd")
   False
   

   Note

   More tests are provided in the password1.txt file.

2. Write the function check_password() that takes two strings with a new and a previous password respectively. The function checks if the new password meets the system requirements. Specifically, the function must return an integer according to the following conditions referring to the new password:

   • If it is equal to the previous password, return 1.

   • If there are not at least 8 characters, return 2.

   • If it does not contain at least one uppercase letter, return 3.

   • In any other case, return 0.

   These conditions must be checked in the order indicated: or example if a new password does not have at least 8 characters and does not contain any uppercase letter, the function will return 2 (not 3). This function must call the previous one.

   See the following examples:

   >>> check_password("Mypassword", "Mypassword")
   1
   >>> check_password("new**3", "Mypassword")
   2
   >>> check_password("newpassword", "Mypassword")
   3
   >>> check_password("newpassWord", "Mypassword")
   0
   

   Note

   More tests are provided in the password2.txt file.
