How to inspect slot wrappers arguments in Python?

Sat Oct 1 11:13:45 EDT 2011

Hi,
I would like to get the list of parameters I need to initialize an AST node.
I'm trying to use the `inspect` module, however it seems I can't use it on a
built-in (native?) class, or else I misunderstood.
I'm using Python 2.7 and tried with Python 3.2.
This is working:
 >>> import inspect
 >>> class C:
 ... def __init__(a,b=4):
 ... self.sum = a + b
 ...
 >>> inspect.getargspec(C.__init__)
 ArgSpec(args=['a', 'b'], varargs=None, keywords=None, defaults=(4,))
This is not working:
 >>> import inspect
 >>> import ast
 >>> inspect.getargspec(ast.If.__init__)
 Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File
"/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/inspect.py",
line 813, in getargspec
 raise TypeError('{!r} is not a Python function'.format(func))
 TypeError: <slot wrapper '__init__' of '_ast.AST' objects> is not a
Python function
I am wondering if there is another way to get these parameters
automatically? (ie. without compiling myself a dict)
Regards,
J. Bilcke
