How to get access to variable that is assigned in function that is inside other class?

Question

I want to get access to an variable from function that is inside other class. How can i do it? I've tried multiple "possible" solutions, but I cant still find it out.

class Class(object):
    def assign(self):
        self.result = 'passed'

print(Class.result)
print(Class.assign().result)

Answer 1

class Class(object):
    def assign(self):
        self.result = 'passed'
        return self.result

object = Class() 
print(object.assign())

this code return the self.result variable

Answer 2

To access the attribute you first need to create an instance of the class, then execute the method in order to create the attribute and finally you can access it:

class Class(object):
    def assign(self):
        self.result = 'passed'

obj = Class()
obj.assign()
print(obj.result)
