  • Python Success Stories

    ...Python - one stop shopping development plus platform independence I used Python before and it seemed to have the potential to do all the required coding and was a programming language that I enjoyed using. I was not entirely confident about some parts of the task, especially building a graphical user interface, but decided to face my fears, trusting to Python's maturity, powerful libraries, and third-party support. The SPE editor together with Python's interpreted nature proved especially valua...

  • Python Patterns - An Optimization Anecdote

    ...Python, but it doesn't hurt repeating it, since it can save a lot of work. :-) Small is beautiful. Given Python's hefty charges for bytecode instructions and variable look-up, it rarely pays off to add extra tests to save a little bit of work. Use intrinsic operations. An implied loop in map() is faster than an explicit for loop; a while loop with an explicit loop counter is even slower. Avoid calling functions written in Python in your inner loop. This includes lambdas. In-li...

  • Python Success Stories

    ...Python? The author had two reasons to undertake this project: To save time keeping up with IT related news. To learn Python. DevNet is a fairly simple application, so it was appropriate as a first project while learning Python. The first prototype version of DevNet used Quixote's PTL for templating and had no database. Python made development of this prototype very rapid, despite the author's initial unfamiliarity with the language. After this was completed, the rapid development nature of Py...

  • Debugging Reference Count Problems

    ...python-list@cwi.nl Date: Wed, 27 May 1998 11:09:40 -0400 Mike Fletcher wrote a number of posts about debugging C code that bombs, probably because of reference count problems. His approach to debugging this problem seems typical, but I think it's not very productive, so I would like to suggest a different approach. Basically, it's often more productive to read your code carefully and reason about it than it is to use a bunch of generic debugging techniques. (Those techniques are ve...
