1. Bank Project

In this project you will have 3 files:

• bank.py
• client.py
• main.py

bank.py

• You will have class Bank. This bank will have instance variable name and class variable clients list. Initially this list will be empty.
• This class will have method add_client method which appends the client to list
• And lastly this class will have authentication method which takes name and account_number as parameters and authenticates the client

client.py

• You will have class Client inside this file.
• Class Client will have account_number, name, total_amount attributes
• __init__ method will initialize these variables, it will take name and total_amount as params and will assign a random 5 digit int to account_number
• Lastly this class will have withdraw, deposit and balance methods.

main.py

• This class initially will create a bank object with a name you choose and then will print the following menu (it should print this menu, until user says exit) [hint: use while loop]:

Choose an option:

    1. Open new bank account

If input is 4, it goes back to other menu.

• And lastly, in the main menu, if user input is 3: close the program

1.2. UML

Draw Use Case and Class Diagrams for this project.

2. UML Class Diagram

Consider the code in file uml_class.py. Draw the UML Class Diagram corresponding to the Python code. You may assume the code compiles, all imports are taken care of, and all classes reside in the same package.

3. UML Use Case Diagram

Draw the UML Use Case Diagram for the followig scenario:

As a lecturer at a university, I am able to manage my exams and register the grades. 
For both these actions, I should always login first with my credentials, followed by a confirmation via an SMS code. 
When I am registering new exam results, I must confirm this action again when my session is older than five minutes. 
When I want to manage my exam, I can choose to either change its date or room.
