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.
add leading zeros to a variable?

I have a variable incrementing in a loop that is appended to a file name, so they are outputted like: file1.bmp, file2.bmp etc.. though I need them like this: file001.bmp, file002.bmp. I tried doing set var [printf %03d $var] but the variable it returns is always empty.

Have you tried replacing printf with format?
