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.

The thing about teaching examples is that they never do exactly what you want - you need to learn from them and adapt them.

You want to:
a) spawn a process and save its spawn_id
b) spawn the second process and save its spawn_id

Then when you want to send or expect from the first process, you can restore its spawn_id, and when you want to send or expect from the second process you can restore its spawn_id.

as an ALTERNATIVE to this last step, you can use the -i option on expect to tell in which processes (in a list if you wish) to expect from.

Hope that clarifies it ... the examples show some of these things, and your course notes (if you or a colleague have been on one of our courses) will give you a lot better / fuller description.
