Random Python Feature

[ichabod801]

I'm working on an interface where the user selects functions. But some of those functions are meta-functions that create the function you want. But the meta-functions can have different types of parameters. How do I validate them? The parameter names are pretty consistent, so I can base the validation off the parameter names. But how do I get the parameter names?

Now, because of the way I write my docstrings, I could write something to parse func.__doc__ and return the parameter names. But is there a way to get that information straight from the function object? It turns out there is:

func.__code__.co_varnames[:func.__code__.co_argcount]

I love Python.
