Criticism on one of my first completed programs in Python

[Zombie_Programming]

This program is supposed to mimic, in a way, a banking program. Essentially it allows the user to login using a 12-digit pre-generated account number and a user-created PIN. If the user doesn't have an account, the user can register with the bank and get an account number. Once the user is logged in, they can make withdrawals, deposits and view a transaction log. It also allows them to log out of the system which will take them back to the login screen. I know the code is probably messy but I would really love feedback on how I can improve on this in the future.

The code is split into three files:

My function library(Called bankAccount):

Then this is my main file.

import bankAccount, datetime, os
from Account import Account

def main():
    while True:
        acctNum, PIN = bankAccount.login()

        # Create User Account object
        userAccount = Account(acctNum, PIN)

        while True:
            os.system("CLS")
            userMenu = bankAccount.showUserMenu(userAccount.getName(), userAccount.getBalance())
            if userMenu == 'Deposit':
                userAccount.makeDeposit()
            if userMenu == 'Withdrawal':
                userAccount.makeWithdrawal()
            if userMenu == 'Transaction Log':
                userAccount.getTransLog()
            if userMenu == 'Logout':
                os.system("cls")
                break
main()
