example. Initialize the 2 bank accounts with 0 initial balance.
• Implement four methods
def deposit (self, amount, account)
. def withdraw (self, amount, account)
• def transfer (self, amount, account)
def getBalance (self, account)

For a transfer , it indicates the account from which the money is taken; the money is automatically transferred to the other account.

• A run for the above test program will result in the following output
Saving balance =
5000.0
Checking balance = 2500.0
