Part Two: Exercise 4: Password Manager

In this exercise, we create a simple password manager using lists in Python 3. Using lists allows us to add and/or remove passwords from the lists. We can use it for PINs as well.

When the user inputs a password or PIN that is in the list, the message ‘Access Granted’ is displayed.

Else if the password or PIN is not in the list, the message ‘Access Denied' is displayed.

 

You can compare with my codes below:

 

passwords = [9001, 9002, 9003]
p = int(input('Enter password>'))

if p in passwords:
    print('Access Granted')
else:
    print('Assess Denied!')

 

We can add to the list by using the .append method and the new password will be included to the list.

 

passwords = [9001, 9002, 9003]

passwords.append(9004)
p = int(input('Enter password>'))

if p in passwords:
    print('Access Granted')
else:
    print('Assess Denied!')

We can delete a password from the list using the .remove method. After removing a password, if we try to input it we would get the message ‘Access Denied’

 

passwords = [9001, 9002, 9003]

passwords.append(9004)

passwords.remove(9001)
p = int(input('Enter password>'))

if p in passwords:
    print('Access Granted')
else:
    print('Assess Denied!')

   We can do more creative things with the password manager when writing specific codes.
