why do i get error for creating an object?

Question

class Person:

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

    rahul = Person(100)

error:

   rahul = Person(100)    
NameError: name 'Person' is not defined

can someone please tell me what the problem is with this simple code?

Answer 1

You are calling Person while the class is still being created (and before the class object is bound to the name Person ). If raul really is supposed to be a class attribute of Person , you'll have to assign it after the class is defined.

class Person:

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

Person.rahul = Person(100)

Answer 2

我想象rahul = Person(100)不应该缩进...
