Hi,
I'd like to know if there's a way to check if an object is a sequence,
or an iterable. Something like issequence() or isiterable().
Does something like that exist? (Something which, in case of iterable,
doesn't consume the first element of the iterable)
Regards,
--Tim

How about
try: it = iter(possible_iterable)
except TypeError: bail()

Tim,
An object is iterable if it implements the iterator protocol. A good
enough check to see if it does is to check for the presense of the
__iter__() method. The way to do it is:
hasattr(object,'__iter__')
You are correct in the fact that you check if an object is iterable
rather than using

Tim,

There are presently two iterator protocols. The old one will be likely be
dropped in 3.0 (currently being discussed).
. A good
enough check to see
