getargs = lambda func: (func.func_code.co_varnames[:func.func_code.co_argcount])

Example Session

#Example Session

getargs = lambda func: (func.func_code.co_varnames[:func.func_code.co_argcount])
def addition(x,y):
    return x+y
print getargs(addition)
#('x', 'y')

Yep, it’s really that simple. No weird exec functions needed, no intrusive introspection via the disassembler.
