Python comment utiliser __lt__

"""
Magic method __lt__ stands for less than. So this magic method defines or 
overwrites what should "<" sign do with objects.
"""

class Test:
    def __init__(self, x):
        self.x = x
    
    def __lt__(self, other):
        """
		Compares attribute "x" of objects, self stands for 1st object
		and other stands for object after "<" sign. (so t is self and t2 other)
		"""
        return self.x < other.x	# Should be used on objects of the same type

t = Test(5)
t2 = Test(2)
print(t < t2)	# Now I call the __lt__ method by using "<" sign.
