My code here is in Python and the goal is to create a BankApp where the user is suppose to enter their username and password and its suppose to show the balance but I forgot to add the information that is suppose to be implemented in my code as shown below.  userName  passWord   Balance ======================== Mike        sorat1237#      350 Jane        para432@4     400 Steve      asora8731%    500 Its also suppose to do down the following.
