Question

I don't known error for this code. Please explain for me.

class BankAccount:
def __init__(self, balance):
self._balance = balance

def __repr__(self):
return "Account Balance: {}".format(self._balance)

def deposit(self, amount):
#your code goes here
self.amount = amount
return self._balance + self.amount

acc = BankAccount(0)
acc.deposit(int(input()))
print(acc)

Answer 1

Thank you. It works. Yes, _balance is property, i was confused. But i don't know my code is error. Please explain for me.

Answer 2

Is this a challenge? if so, I can't tell you unless I also know the instruction.

Challenges usually requires you to do the exact instruction, no more and no less. So I suggest you to pay extra attention to the requirement, and see if your code gives the exact output as instructed.

Answer 3

Try to update account _balance inside deposit() method.

def deposit( self, amount ):
self._balance += amount

If there is anything to be returned, you probably want to return a boolean, indicating whether the deposit process was valid e.g. <amount> is greater than zero.

Answer 4

_balance method is private methods

Answer 5

_balance is a property, not a method.

I edited my previous response, missed the underscore for <_balance> property name.

Answer 6

It's just a practice in the "Python Core" course.
