Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

signature

✓ from inspect2 import signature

✗ from inspect import signature

Python <3.4 has no inspect.signature; use inspect2 for backport.

Use inspect2.signature to get callable signatures on Python 2.7–3.5.

from inspect2 import signature def foo(a, b=1): return a + b sig = signature(foo) print(sig.parameters['a'].default is None) print(sig.parameters['b'].default)

Debug

Known issues

deprecatedinspect2 is only needed for Python 2.7–3.5. Python 3.6+ natively includes inspect.signature; using inspect2 on Python 3.6+ may cause import conflicts.

fix

Use standard library 'inspect' on Python 3.6+.

affects: >=3.6

gotchainspect2 does not override the built-in inspect module. You must explicitly import from inspect2.

fix

Use 'from inspect2 import ...' instead of relying on inspect being patched.

affects: all

Errors

Common errors & fixes

ImportError: cannot import name 'signature' from 'inspect'

Python <3.4 has no inspect.signature, or Python 2.7's inspect does not have signature.

fix

Install inspect2 and use 'from inspect2 import signature'.

TypeError: signature() got an unexpected keyword argument 'follow_wrapped'

inspect2 version 0.1.2 does not support follow_wrapped parameter (Python 3.5+).

fix

Omit follow_wrapped or upgrade to Python 3.6+ to use inspect.signature.
