Call function without optional arguments if they are None

Question

There\'s a function which takes optional arguments.

def alpha(p1=\"foo\", p2=\"bar\"):
     print(\'{0},{1}\'.format(p1, p2))

Let me iterat

Answer 1

You could inspect the default values via alpha.__defaults__ and then use them instead of None. That way you circumvent the hard-coding of default values:

>>> args = [None]
>>> alpha('FOO', *[x if x is not None else y for x, y in zip(args, alpha.__defaults__[1:])])
