SoloLearn's lesson misunderstanding

Question

Code:
class GameObject:
class_name = ""
desc = ""
objects = {}

def __init__(self, name):
self.name = name
GameObject.objects[self.class_name] = self

def get_desc(self):
return self.class_name + "\n" + self.desc

class Goblin(GameObject):
class_name = "goblin"
desc = "A foul creature"

goblin = Goblin("Gobbly")

def examine(noun):
if noun in GameObject.objects:
return GameObject.objects[noun].get_desc()
else:
return "There is no {} here.".format(noun)

Question:
I don't understand why first line with "GameObject.objects..." in this code was written without any tabs?
If it's in the definition of class GameObject it should be written with one tab before the line code, but it was written as something after the class definition.
It will be maybe okay, but after that is "def get_desc" with one tab, so get_desc is in class.

Answer 1

Tabs and spaces are not required for code to run. You often see this with websites that they'll have .min versions of files that take out all spacing to make the file load faster.

Tabs and spaces are simply used to make the code more readable to humans.

Answer 2

George Raymond how programm , for example, understand where functions are ended without tabs and spaces?
Or I don't understand something
