Question

You are going to write a program (In Python) called BankApp to simulate a banking application.
The information needed for this project are stored in a text file. Those are:
usernames, passwords, and balances.
Your program should read username, passwords, and balances for each customer, and
store them into three lists.
userName (string), passWord(string), balances(float)
The txt file with information is provided as UserInformtion.txt
Example: This will demonstrate if file only contains information of 3 customers. You
could add more users into the file.
userName passWord Balance

When a user runs your program, it should ask for the username and password
first. Check if the user matches a customer in the bank with the information
provided. Remember username and password should be case sensitive.
After asking for the user name, and password display a menu with the following
options and ask the user for input (Use a While Loop).

Type D to deposit money
Type W to withdraw money
Type B to display Balance
Type C to change user, display user name
Type A to add new client
Type E to exit
If the user types D
(Deposit Function) Ask the user to enter the amount to deposit.
Then call the Deposit Function, passing the deposit amount as a parameter. The
function should update the Balance.
Then display the new balance (this should happen by calling the ShowBalance
function).
Then display the menu again
If the user types W
(Withdraw Function) Ask the user to enter the amount he/she wants to withdraw.
Before calling the withdraw function, make sure there is enough balance. Call
the ShowBalance function before Withdraw function!!
Then call the Withdraw Function, passing the withdraw amount as a parameter.
The function should update the Balance.
Display the new balance to the user.
Then display the menu again

If the user enters B
(ShowBalance Function)
Display the Balance.
If the user enters C
(ChangeUser Function) Ask for the user name and change to a different
customer.
If the user enters A (AddNewUser function) Ask for username, password,
and balance. These information will be added to the appropriate lists which
later on will be transfered to the UserInformation.txt
If the user types any other option: Prompt the user that option is invalid
If the user types E then
Terminate the program and update the UserInformtion.txt with the correct
updated balances.
PS: You program must keep displaying the menu until the user types the option
E, to exit the program.
