Pass an object to a class, then make an object of it and pass again

[TomasAm]

class Fabric:
    def __init__(self, humans):
        self.Body = humans
    def set_eyes(self, value)
        self.Body.top.eyes = value
        print(self.Body.top.eyes)

then fabric.set_eyes(4).

you need to use self, not fabric. self is the instance, which is passed automatically. But this is anti-pattern in python. Normally we don't need need setters and getters just to modify a property. We will do fabric.Body.top.eyes = 4 outside the class, without the need to define Fabric.set_eyes() method.

Thank you, now it makes sense! I will read more about this "anti-pattern in python."
