Getting the docstring of a property

[Andrew Durdin]

How do you get the docstring of a property? Suppose I have the following:

class Foo:
def _prop_get(self):
return 1
prop = property(_prop_get, doc="This is the docstring")

foo = Foo()
print foo.prop
print foo.prop.__doc__

This will display "1", followed by the docstring for an integer (which
is the docstring for the int() function). How can I get the property's
docstring as defined in the property() function?

You tried to access it from the instance. However, accessing it from the
instance invoked the property, returning 1, before it attempted to
access the docstring.

You need to get it from the class. That is:

Foo.prop.__doc__

should do what you want.
