python access class method from class variable

Question

I'm trying to access a class method from the class variable as follows:

class A():
    a = A.b()

    @classmethod
    def b():
        return 5


print A.a

but i get the error:

NameError: name 'A' is not defined

What am I doing wrong?

You're using A within A. You should, first of all, put all of your initialization in an __init__ definition. And then use self to call upon itself.

class A():
    def __init__ (self):
        self.a = self.b()

    @classmethod
    def b(cls):
        return 5

print A().a

thanks, I'm familiar with the other approach, but I want to use the class variable for this case. How can I achieve that behavior while using class variable. Should I define the method outside of the class?
