  • deposit_checking(self, amount) - add parameter amount to the checking account balance (only if positive)
  • deposit_savings(self, amount) - add parameter amount to the savings account balance (only if positive)
  • withdraw_checking(self, amount) - subtract parameter amount from the checking account balance (only if positive)
