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.

# Place all the radio buttons in a list. Easier to maintain

$times = array("05:52","07:45","13:35","17:02","21:33");

# The hidden field "completed" is used to check whether the
# form has been completed or is newly put up. If the form HAS
# been completed, then generate the result; if not, simple give
# a placeholder string so that the page has the same layout.

/* Notes on the HTML:

a) Unless you are sure of your code, it's dangerous to
use highlight_file on a public site - you're revealing
any security risks and also baffling your readers with

b) The form tag defaults to submitting the form back to
the URL from which the page was generated.  I could have
used a method=POST attribute and it would have worked
just as well, and that would have removed the "Yuk factor"
from the location line.  I let it run with the get method
(URL limit 1k bytes) so that you can see how it works.
