I have a vague feeling you're trying to write C++ in Python, and that
usually doesn't work well. In general, C++ (and Java) is all about
types of things, while Python is more about capabilities of things.
What do you mean by a "simple type" as opposed to a "complex type"? I
suspect by "complex type" you really mean "tuple or list". If that's
the case, you can certainly do something like:
def myFunc (arg):
if isinstance (arg, tuple) or isinstance (arg, list):
blah, blah, blah
But before you do that, you might want to think if this is really what
you want to do. What, exactly, is it that you're trying to do that
requires you to know what type of object an argument is?
