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?
# bank account class class 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.balance def 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()
