New submission from Chris Jerdonek <chris.jerdonek at gmail.com>:

functools.partial objects have no __qualname__ attribute. This means, for example, that code expecting a callable that logs the __qualname__ attribute can break when passed a functools.partial object.


>>> import functools
>>> int.__qualname__
>>> p = functools.partial(int)
>>> p.__qualname__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'functools.partial' object has no attribute '__qualname__'
