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.
repeat until in Lua - a one or more rather than a zero or more loop

The "repeat until" structure in Lua provides a loop with condition checking at the end - in other words, it's a "one or more times" loop, unlike while which is a "zero or more times" loop.

Syntax - straightforward; example:

  repeat
    io.write("How many people? ")
    said = tonumber(io.read())
  until said


note - no do, no then and no end. Sample program [here].
