|

* New function: the :mod:`inspect` module's :func:`~inspect.getcallargs`
|
||||
takes a callable and its positional and keyword arguments,
|
||||
and figures out which of the callable's parameters will receive each argument,
|
||||
returning a dictionary mapping argument names to their values. For example::
|
||||
|
||||
>>> from inspect import getcallargs
|
||||
>>> def f(a, b=1, *pos, **named):
|
||||
... pass
|
||||
>>> getcallargs(f, 1, 2, 3)
|
||||
{'a': 1, 'named': {}, 'b': 2, 'pos': (3,)}
|
||||
>>> getcallargs(f, a=2, x=4)
|
||||
{'a': 2, 'named': {'x': 4}, 'b': 1, 'pos': ()}
|
||||
>>> getcallargs(f)

Traceback (most recent call last):
