Division of integers performs a "floor division" that rounds the result down to a whole number. If you want a floating point result, you'll need to specify that you're working with floats: 5.0/-2 or float(5)/-2 > 2) list assignment handling, pointing two vars to the same list: See http://effbot.org/zone/python-objects.htm . > 3) ambiguous use of the form: this.that() The form "this.that" *always* means the same: It refers to the attribute called "that" of the object called "this". This may yield seemingly different meanings depending on what type of object "this" is, but the basic mechanism is always the same. The main source of your confusion seems to stem from the fact that join() was decided somewhat non-intuitively to be a method of string instances. By the way, the next time you have a number of unrelated questions, please consider posting them in separate messages. That allows you to pick a more descriptive subject line for each message, and it makes the ensuing conversations easier to follow.
