Hi Adam, I believe a general rule of programming is: don't optimize until you know you need to. I would advise using dictionaries for simplicity. If the program turns out slower than you would like, you can use profiling tools to figure out where in the code it is spending most of its time. If this turns out to involve dictionary lookups, you could then look at changing to Numpy (hint: you could use the timeit module to benchmark dictionary access against Numpy arrays). If your program design is good, the change should be too hard. http://en.wikipedia.org/wiki/Optimization_(computer_science)#When_to_optimize -- John. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
