I am learning Python and in particular learning about classes. Since I'm self teaching, I'd appreciate any feedback and constructive criticism.I have a couple specific questions:In Python you can have multiple functions and classes in a single file (module), but is it considered bad practice to do so?Python doesn't have private, so is there a point to having accessor methods like I do below?My IDE suggest I put a comment beneath each function signature. Is it still good to do this when the functions are short and simple, like withdraw(x) in a bank account? BankAccount.py# bank account classclass BankAccount:    def __init__(self, name, balance=0.00):        self.name = name        self.balance = balance    def deposit(self, amount):        make a deposit        self.balance += amount    def withdraw(self, amount):        make a withdraw        if amount > self.balance:            raise ValueError(insufficient funds)        self.balance -= amount    def get_balance(self): #are accessor methods needed in Python?        check the balance        return self.balancedef main():    customer1 = BankAccount('Alex')    print(customer1.get_balance())    customer1.deposit(100)    customer1.withdraw(30)    print(customer1.get_balance())    customer2 = BankAccount('Sam', 200)    print(customer2.get_balance())if __name__ == __main__:    main()
