The following example crashes Python 3.6:
from functools import partialmethod
import inspect
class T:
g = partialmethod((lambda self, x: x), 1)
print(T().g()) # Correctly returns 1.
print(T.g(T())) # Correctly returns 1.
print(inspect.signature(T.g)) # Crashes.
with
File "/usr/lib/python3.6/inspect.py", line 3036, in signature
return Signature.from_callable(obj, follow_wrapped=follow_wrapped)
File "/usr/lib/python3.6/inspect.py", line 2786, in from_callable
follow_wrapper_chains=follow_wrapped)
File "/usr/lib/python3.6/inspect.py", line 2254, in _signature_from_callable
assert first_wrapped_param is not sig_params[0]

This is not a crash, but an assertion failure. The assertion was added in issue30149. |

Yeah, that assertion needs to be tweaked a little bit. Created a PR. |
