Python beginner's class. I have a question

class BankAccount:

no_of_accounts = 0

def __init__(self, name, balance = 0):
    self.name = name
    if balance >= 0:
        self.balance = balance
    else:
        self.balance = 0 
def show_name(self):
    if self.name:
        print(self.name)
def show_balance(self):
    if self.balance:
        print(self.balance)
def deposit(self,amount):
    if amount >= 0:
        if isinstance(amount,int) == True:
            self.balance += amount
def withdraw(self,amount):
    if amount >= 0 and self.balance >= amount:
        self.balance -= amount

In this code, I want to add 1 to no_of_accounts each time an object is created in a class, what should I do? Every time an object is created, the init method is used, so if you add no_of_accounts += 1 inside the init method, no_of_accounts are class variables, so an error appears.

Class variable is class name.Accesses by variable name.


class BankAccount:

    no_of_accounts = 0

    def __init__(self, name, balance = 0):
        BankAccount.no_of_accounts += 1

        self.name = name
        if balance >= 0:
            self.balance = balance
        else:
            self.balance = 0

You can do it with.
