How does the @property decorator work in Python?

Question

I would like to understand how the built-in function property works. What confuses me is that property can also be used as a decorator, but it only

Answer 1

The first part is simple:

@property
def x(self): ...

is the same as

def x(self): ...
x = property(x)

• which, in turn, is the simplified syntax for creating a property with just a getter.

The next step would be to extend this property with a setter and a deleter. And this happens with the appropriate methods:

@x.setter
def x(self, value): ...

returns a new property which inherits everything from the old x plus the given setter.

x.deleter works the same way.
