At first you say you want a list, later you say you want an array. They're two different things. Arrays are variable-length and can be heterogeneous. If what you really want is a fixed-length, homogeneous array, then use an array instead of a list: http://docs.python.org/library/array.html > If I declare a class with some member variables, is is strictly > necessary for me to qualify those members in a method in that class?

That's a matter of opinion. Some of us _like_ self.f since it explicitly shows the reader that f isn't a global or local but a class or instance variable. Any time you make the reader/maintainer guess what something is, that's a bug waiting to happen. > Is there any way around this or is that simply "a matter of life"? Well, that's how Python works. I won't comment on "life". -- Grant Edwards grant.b.edwards Yow! I feel like a wet at parking meter on Darvon! gmail.com -- http://mail.python.org/mailman/listinfo/python-list
