[New-bugs-announce] [issue46730] Please consider mentioning property without setter when an attribute can't be set

[Neil Girdhar]

New submission from Neil Girdhar <mistersheik at gmail.com>:

class C:
    @property
    def f(self) -> int:
        return 2

class D(C):
    pass

D().f = 2

Gives:

Traceback (most recent call last):
  File "/home/neil/src/cmm/a.py", line 10, in <module>
    D().f = 2
AttributeError: can't set attribute 'f'

This can be a pain to debug when the property is buried in a base class.  Would it make sense to mention the reason why the attribute can't be set, namely that it's on a property without a setter?
