Delete attributes from an instance in Python

del, a Python built-in function, deletes the instance's property.

class Account:

    def __init__(self, name):
        self.name = name

    @staticmethod
    def agree():
        print('I agree.')


Account.agree()  # I agree.

a = Account(name='Kyle')

del a.name

print(a.name)
# AttributeError: 'Account' object has no attribute 'name'

After deleting name property, we can't access a.name but assign a value to it.

class Account:

    def __init__(self, name):
        self.name = name

    @staticmethod
    def agree():
        print('I agree.')


Account.agree()  # I agree.

a = Account(name='Kyle')

del a.name

a.name = 'Stan'

print(a.name)  # Stan
