[New-bugs-announce] [issue4795] inspect.isgeneratorfunction inconsistent with other inspect functions

[Steven D'Aprano]

New submission from Steven D'Aprano <steve at pearwood.info>:

The inspect isSOMETHING() functions all return True or False, except 
for isgeneratorfunction(), which returns True or None.

The body of the function is very brief:

if (isfunction(object) or ismethod(object)) and \
        object.func_code.co_flags & CO_GENERATOR:
        return True

The behaviour can be made consistent with the other routines by either 
appending "else: return False", or changing the body to:

return bool(
  (isfunction(object) or ismethod(object)) and
   object.func_code.co_flags & CO_GENERATOR)
