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

For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, 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:

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

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

... 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++.
