Yes, except that it's not really very Pythonic and we're the number of
script kiddies out there picking up the language we need to try and
encourage the good stuff.

No! strings have got the split() method (since Python 1.6)

Assuming the criteria are coming from some web form there should be no
need to split a string, they should already be available as a list.

I'd actually use upper() in the DB query but it doesn't make much

Do not use a PythonScript to generate user readable output! Use it simply
to control your SQL query and pass the results to a template to display
which look something like this.
<tal:block tal:define="results context/myScript">
<h3 tal:repeat="ligne results" tal:content="ligne/id"></h3>
As you actually wish to list the results by criteria then you should pass
the criteria to the script in a template loop but I'll leave that to you.
