Retiring, March 2020 - sorry, you have missed our final public course.
The Coronavirus situation has lead us to suspend public training - which was on the cards anyway, with no plans to resume

Please ask about private 'maintenance' training for Python, Tcl, Perl, PHP, Lua, etc
Happily continuing private consultancy / programming work
 
Python in an afternoon - a lecture for experienced programmers

Last Friday afternoon I was set a challenge - to present Python in three hours to a group of 20 very experience programmers who, however, knew nothing about this particular language.

London Bound - an HST seatThe session was in Central London - my directions started off with "Get off the Tube at Oxford Circus", so Londoners will know just how central I mean - so I took First Great Western's Penzance express from Westbury into Paddington. It's great to have power at your seat for laptops these days, though the new airline style seats in second class (oops - standard class!) are a bit tight for working on, and the computer jump horribly when the guy in the seat ahead gets up or flops down.


"Python in a nutshell" - no - that's NOT what I entitled the talk, but I went through the various features that will be mainstream for this group (I had had their applications described to me ahead of time), and I concluded with an example which - in less that 1500 bytes including comments - shows a short and simple use of many of the features os the language.

• Variables and Loops
• Comments
• Lists, Tuples, Dictionary
• Functions, Modules, Object use
• Variable scope
• Documentation Strings
• Regular strings, triple quoted strings and raw strings
• Regular Expressions
• Formatted String Outputs
• File Statuses and File Handling.
• Prompting and reading from STDIN
• Exception handling and error exiting

In some horror, I notice that my example doesn't have a single if statement in it but - hey - I don't think I did too badly in getting so much in to a practical piece of code ... [source code here]

How did the afternoon go? Well - I enjoyed it and my whole audience remained, right through to a quarter past five when I finished. A handful of excellent questions afterwards. And a comment from my contact there, who isn't technical himself and had meetings during the afternoon - "Graham - I came back at about five and looked in through the window. The degree of concentration after three hours from everyone was quite remarkable".
