Python function signatures from PEP362 for Python 2.6, 2.7 and 3.2+

Project description

funcsigs is a backport of the PEP 362 function signature features from Python 3.3’s inspect module. The backport is compatible with Python 2.6, 2.7 as well as 3.2 and up.

Latest PyPI version

Documentation

The reference documentation is standard library documentation for the inspect module in Python3. This documentation has been included in the funcsigs package documentation hosted on Read The Docs.

Example

To obtain a signature object, pass the target function to the funcsigs.signature function.

>>> from funcsigs import signature
>>> def foo(a, b=None, *args, **kwargs):
...     pass

>>> sig = signature(foo)

For the details of the signature object, refer to the either the package of standard library documentation.

Compatability

The funcsigs backport has been tested against:

  • CPython 2.6
  • CPython 2.7
  • CPython 3.2
  • PyPy 1.9

Continuous integration testing is provided by Travis CI.

Under Python 2.x there is a compatability issue when a function is assigned to the __wrapped__ property of a class after it has been constructed. Similiarily there under PyPy directly passing the __call__ method of a builtin is also a compatability issues. Otherwise the functionality is believed to be uniform between both Python2 and Python3.
