This is done in PYTHON

you need to complete all of the TODO items, which include

• __repr__ for BankAccount, SavingsAccount, CheckingAccount such that it displays the class name (__class__.__name__) followed by the instance variables for that class in the format [variable=value]. Note that the __repr__ for BankAccount will display the class name and the subclasses will concatenate to its superclasses __repr__ its own instance variables.

• You need to write the code for the TimeDepositAccount class, based on the UML diagram specification given on Canvas. A TimeDepositAccount is a savings account that you have agreed to keep the money in until it matures. If you withdraw money before its maturity, an early withdrawal penalty will be charged.
