Is there a way to print out a function's parameter list? For example:
def func(a, b, c):
pass
print_func_parametes(func)
Which will produce something like:
["a", "b", "c"]

Use the inspect module.
>>> import inspect
>>> inspect.getargspec(func)
(['a', 'b', 'c'], None, None, None)
The first part of returned tuple is what you're looking for.

Read the source. Seriously. Python programs and libraries are provided as source. You can read the source.

Unless the O.P. is writing some code analysis/development tool, I am guessing that whatever they need it for will end in disaster.
You might also try the built-in help() function, which will provide you not only with a list of the named parameters, but also a description of func() if you provided a docstring:
>>> def func(a, b, c):
... """do x to a,b,c and return the result"""
... pass
...
>>> help(func)
gives you
Help on function func in module __main__:
func(a, b, c)
do x to a,b,c and return the result
Most modules are provided with at least some sort of built-in documentation.
