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.
Flask - complete MVC site to navigate around a data set

A full demonstration from today - Flask Model, View and Controller. There's an index page listing links to all UK railway stations, and individual pages (via a 3 letter code URL) for each station. Here's the log of a session:



and some of the pages in that session:


 

 


The main router and controller: stations.py
The model: station_model.py
Data for the model: rstats2014.xyz
The base view template basestation.html
The template for the index allstations.html
And the template for individual stations astation.html
