Python comment utiliser __Treediv__

"""
Magic method __truediv__ is called when a "/" is used on any object. 
Given example shows what I mean: print(some_object / other_object)
This may give error often, so that means given objects don't have __truediv__ method
"""

class Test:
    def __init__(self, x):
        self.x = x
    
    def __truediv__(self, other):
    	""" 
    	self represents the object that is first and other is object after
    	"/" sign. What I say here is that I expect to have attribute "x" 
    	in both objects and I will try to divide them. This SHOULD BE
    	used for objects of the same type.
    	"""
    	return self.x / other.x

t = Test(5)
t2 = Test(2)	# Now I can divide these two objects.
print(t / t2)	# 2.5, without __truediv__ the object doesn't understand the "/" sign.
