No:

In [4]: inspect.getargspec(min)
---------------------------------------------------------------------------
exceptions.TypeError                                 Traceback (most recent 
call last)

/home/fperez/<ipython console>

/usr/lib/python2.3/inspect.py in getargspec(func)
     653         func = func.im_func
     654     if not isfunction(func):
--> 655         raise TypeError('arg is not a Python function')
     656     args, varargs, varkw = getargs(func.func_code)
     657     return args, varargs, varkw, func.func_defaults

TypeError: arg is not a Python function


getargspec fails with extension code, it only works with pure-python functions.
