From: http://www.faqs.org/docs/diveintopython/odbchelper_tuple.html 1 You can’t add elements to a tuple. Tuples have no append or extend method. 2 You can’t remove elements from a tuple. Tuples have no remove or pop method. 3 You can’t find elements in a tuple. Tuples have no index method. 4 You can, however, use in to see if an element exists in the tuple. So what are tuples good for? * Tuples are faster than lists. If you’re defining a constant set of values and all you’re ever going to do with it is iterate through it, use a tuple instead of a list. * Remember I said that dictionary keys can be integers, strings, and “a few other types”? Tuples are one of those types. Tuples can be used as keys in a dictionary, but lists can’t.[2] * Tuples are used in string formatting, as we’ll see shortly. -- http://mail.python.org/mailman/listinfo/python-list
