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.
Lua examples, Lua Courses

Programming training is much more effective if the delegates are shown how a particular program is written, rather than just the final result ... show them just the final result and they'll ask "but how did you come up with that?"

So whenever possible, I write new examples in front of my delegates - spill my guts if you like, describing what I'm writing, and what my logic is behind it. The result is that - by the end of the course - I have a whole folder full of new examples which I then sent through (zipped) to the delegates for them to use as post-course material in addition to the more formal printed notes.

After the three day Lua course in central London that finished yesterday evening, I took the long way round on my way home - a leisurely train ride via Waterloo and Salisbury to Trowbridge, and that gave me the opportunity to tidy up my examples - add in some more comments, and some sample output ... and I've added the better ones to our web resources - and here that are:

furry - Calculations / good variable naming conventions
prncr - Output of a prompt without a new line
wcd - exchange rate loop
whilly - while loop - break and alternative
andor - combining and / or operators
moopark - theme park entrance prices
stem - simple string function use
tat - pairs v ipairs
cleversort - Sorting using a user defined comparator
party - building up a table as data is entered
fav - function as table member - polymorphic tables
dress1 - function call - simple example
dress2 - local variables in a function
dress3 - conditional function definition
fsr - variable number and type of parameters
cuboid - Using a demonstration class
newCube.lua - A demonstration class definition
iiapc - Pattern Match to Postcode, with capture
skill_lister - Read, analyse, sort data from file

I started this article saying how much more effective training is when you see he examples developed interactively, and yet I have now shown them to you as "final results only". However, with the comments I have added they are still a good resource for delegates who have taken some steps in Lua already, or who are geeks who lap up this stuff. If you look at them and think "I wish I could write code like that" ... the come along on our public Lua course or book me for a private course if you've a group of four or more.
