Part 1 Bank Accounts
Task 1 Deposit
Add a method deposit() to deposit some money into the account.
>>> myAcc = BankAccount('Alan',1000)
>>> myAcc.showBalance()
Your balance is $1000.00
>>> myAcc.deposit(200)
>>> myAcc.deposit(400)
>>> myAcc.showBalance()
Your balance is $1600.00
Task 2 Secure Withdrawal
Add a control measure where a name must be provided for withdrawal and it must match the name in the account.
>>> myAcc = BankAccount('Alan',1000)
>>> myAcc.withdraw('Mary',100)
You are not authorized for this account
>>> myAcc.withdraw('Alan',10000)
Money not enough! You do not have $10000.00
0
>>> myAcc.withdraw('Alan',100)
100
>>> myAcc.showBalance() Your balance is $900.00
Task 3 Interest
Add an attribute for the interest rate and initialize it in the constructor.
Implement a function oneYearHasPassed() which adds the interest gained after one year to the account.
>>> myAcc = BankAccount('Alan',1000,0.04)
>>> myAcc.showBalance()
Your balance is $1000.00
>>> myAcc.oneYearHasPassed()
>>> myAcc.showBalance()
Your balance is $1040.00
>>> myAcc.oneYearHasPassed()
>>> myAcc.showBalance()
Your balance is $1081.60

Task 4 Minimal Account
Create a MinimalAccount class that behaves the same as the normal BankAccount except that whenever one year has passed, if its balance is less than $1000, a $20 administration fee will be deducted from the account before the annual interest is gained. The balance will never be below zero.
>>> mySonAcc = MinimalAccount('John',40,0.04)
>>> mySonAcc.oneYearHasPassed()
>>> mySonAcc.showBalance()
Your balance is $20.80
>>> mySonAcc.oneYearHasPassed()
>>> mySonAcc.showBalance() Your balance is $0.83
>>> mySonAcc.oneYearHasPassed()
>>> mySonAcc.showBalance() Your balance is $0.00
Extra Tasks
• Method transferTo() in class BankAccount
o Given another account, you can transfer your money to the account
>>> myAcc.transferTo(myWifeAcc,500)
• Method setupGiro() in class BankAccount
o Money will be deducted annually before interest is gained
>>> myAcc = BankAccount('Alan',1100,0.04)
>>> myAcc.setupGiro(40)
>>> myAcc.setupGiro(60)
>>> myAcc.oneYearHasPassed()
>>> myAcc.showBalance()
Your balance is $1040.00

• A new class JointAccount
o An account has two owners and both owners can withdraw money from the account
Part 2 Vehicles
Task 1 Petrol
Let’s try to be more realistic: every vehicle needs some petrol to move. Add a method addPetrol(n) (where?) that adds n litres of petrol into a vehicle. For every “move”, the vehicle will consume one litre of petrol.
>>> myCar.addPetrol(2)
>>> myCar.move()
Move to (0, 80)
>>> myCar.move()
Move to (0, 160)
>>> myCar.move()
Out of petrol. Cannot move.
Task 2 Solar Tank
Implement a class SolarTank that does NOT need petrol. (Pulling your leg?) Just think about how you should organize your class structure.
