If you first write 500 lines of code, and *then* try to run it, it seems you are using a development approach suitable in the 1960's when running a program meant handing a stack of punch cards to a computer operator in a white coat, and then getting the result of the run the next day (if you're lucky). I was taught to write like this as recently as in the late 80's when I was in universtity, but today I typically run my code every ten minutes or so. It's rare that I run the code I work on less frequently than every thirty minutes. In my experience, my current way of developing software leads to higher productivity, better quality and much better predictability in regards to both development time and software performance and features. The way to achieve this is to use lots of automated tests and a development time where you learn to work in small increments. Martin Fowler's book "Refactoring" is a good guide for this, and Python is a very good language to use for this kind of development. Perhaps this might be useful? http://www.thinkware.se/cgi-bin/thinki.cgi/SoftwareTestingWithPython http://thinkware.se/epc2004test/log.html -- http://mail.python.org/mailman/listinfo/python-list
