Lesson 1 in programing - write clean, reuseable and maintainable tidy code

Python and Tcl - public course schedule [here]
Private courses on your site - see [here]
Please ask about maintenance training for Perl, PHP, Lua, etc

I often say to delegates that I train that they could write code that makes the dog's dinner look neat:

The dogs dinner

Really, that's not a good approach to code writing ... for sure, it can be cleaned up ...

Dog eating dinner

... and you can end up with something sparkling tidy ...

Clean Bowl

... but why not write it tidy in the first place?

I stress writing clean, easy to follow, easy to maintain code on all the programming courses that I teach - right through from Learning to program in PHP for delegates who have never programmed before, through PHP Programming which is for delegates who have prior experience, but in other languages, and on to the Object Oriented Programming in PHP and PHP Techniques courses which are more advanced. And this coming week, I'll be following the same good design principles as I teach delegates about the use of "MVC" in PHP, and look at more advanced topics such as caching and testing, much of it under the Zend framework.

Although the example I talk about in this article is PHP, the same applies to our other courses in Perl, Python, Ruby, Lua, Tcl, C and C++.
