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. |
Introspecion in Perl 6
Perl 6 provides introspection - that's the ability for its object to be able to report on methods, attributes and inheritances.
And if you run Perl6 without an input file, it goes into a read - interpret - run cycle with each line you type in, rather like Python, Ruby and Tcl do. So we can experiment easily with that introspection.
