Why can't I access a variable from another class Python

Question

When I run hello printer I get this error

AttributeError: type object 'Setup' has no attribute 'hello'

please help!

hello printer

from rpg import *
print Setup.hello

rpg

class Setup(object):
   def setup(self):
       hello = 5

Answer 1

Either make setup method static or insert self argument.

class Setup(object):
    @staticmethod
    def setup():
        hello = 5
        print hello
Setup.setup()

As its a static method, you don't have to initialize a class. or

class Setup(object):
    def setup(self):
        hello = 5
        print hello
s = Setup()
s.setup()

In this case you will have to create an object of Setup class as you will be accessing the class method.

Answer 2

You define hello in the function setup so it does not belong to the class namespace. To access a class variable you need to define it in the class, not in a function:

class Setup(object):
    hello = 5
