Final answer:
def total_assets(self):
return sum(account.balance for account in self.accounts)
Step-by-step explanation:
The 'total_assets' method for the Bank class is defined as a Python function that utilizes a list comprehension to sum the balances of all 'accounts' within the bank. This method iterates through the accounts attribute of the Bank class, which presumably contains instances of the Account class, and calculates the sum of their balances. The 'sum' function efficiently adds up these balances, providing the total assets of the bank.
This implementation leverages Python's concise syntax and the built-in sum function, making the code readable and efficient. By encapsulating the logic within a method, it promotes code organization and encapsulation, adhering to the principles of object-oriented programming.
The 'total_assets' method efficiently calculates and returns the total assets of the bank by summing the balances of all accounts. This approach enhances code readability and encapsulation within the Bank class. The 'total_assets' method utilizes Python's list comprehension and the sum function to calculate the sum of all account balances, providing a clear and efficient way to determine the overall financial strength of the bank.
