Instance of bankaccount has no depo as memeber

Question

Please someone help me to find out what i am missing here, try to add an input to the existing bankaccount, the error of missing depo as member always show up:
class BankAccount:
def __init__(self, balance):
self._balance = balance

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

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

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

Answer 1

There is no self.depo intialized when you create an instance "acc" .
self refers to the object itself ,it is simply depo , if you want to use self.depo you can put it inside init method with self.depo assigned any value and then assign new value to it in deposit method like
self.depo=depo #when calling deposit method

or it is just a simple value that you are passing as an argument and accessing it as a parameter

depo=depo
