For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Flask - first forms and responses with wtforms

Using Flask, the wtforms module lets you set up your own forms - example [here] with the jinja template [here]. This example sets the for up, but does not handle reponses - indeed, a form submitted back will generate an error 405 and I have used this opportunity to use the app.errorhandler decorator to show custom error messages.

The following example at [here] shows a form that picks up the answers, and uses a template conditional to show either the answers or the form depensing on completion success - the template is [here].
