Sure. Why not? If you're coming from a type-bondage language like
C++ or Java, it probabliy feels strange, but it's the Python way. It
looks
Others may know better ways but the 2 I know of are:
1) If you know that the arguments will be lists or tuples
you can use isinstance().
if not isinsance(arg, (list, tuple):
print "arg must be list or tuple)
2) Or if you not you could see if the argument has next and
__iter__ methods (more g
