Yury Selivanov added the comment: Nathan, consider the following signature:
def foo(a=0:''): pass now, sig.parameters['a'].annotation will be '' and .default will be 0, and they will fail 'if param.annotation or param.default' check. That's why we encourage checks like 'if param.annotation is not param.empty'.
