as the title says, in python, I'm trying to make it so when someone types in a choice (in this case Choice13) then it deletes the old password from the list passwords and adds the new one instead.
passwords = ['mrjoebblock' , 'mrjoefblock' , 'mrjoegblock', 'mrmjoeadmin' ]
if choice == '3':
password = raw_input('Welcome admin! I\'m going to need your password ')
if password == 'mrjoeadmin':
print('Welcome Mr. Joe!')
Choice11 = raw_input('What would you like to do? Press 1 for changing your admin password, 2 for viewing a class\'s comments, or 3 for changing a class\'s password')
if Choice11 == '1':
print('You have chosen to change your password! ')
Choice12 = raw_input('You will need to put in your current password to access this feature ')
if Choice12 == 'mrmajoeadmin':
Choice13 = raw_input('What would you like to change your password to? ')
passwords.remove('mrjoeadmin')
passwords.append = Choice13

append() will place new items in the available space. Lists are sequences that can hold different data types and Python objects, so you can use . append() to add any object to a given list. In this example, you first add an integer number, then a string, and finally a floating-point number.
The Python "AttributeError: 'NoneType' object has no attribute 'append'" occurs when we try to call the append() method on a None value, e.g. assignment from a function that doesn't return anything. To solve the error, make sure to only call append() on list objects.
To append something to a list, you need to call the append method:
passwords.append(Choice13)
As you've seen, assigning to the append method results in an exception as you shouldn't be replacing methods on builtin objects -- (If you want to modify a builtin type, the supported way to do that is via subclassing).

or you could modify the same list slot by doing:
passwords[passwords.index('mrjoeadmin')] = Choice13
