Hi I like to put a for-loop in a try except clause in an html file.
My problem is that the pass from the for loop terminates the try block.

I tried it too and for some weird reason it works.
The missing doublepoint you spotted is in my complete code on my server^^
what I really want to do is: diyplaying a database entry in a table.
this entry varies from no entries to about 10.
I didn't account for the no entries part but I got a
OK I did some further testing and I'm pretty stupid some basic
understanding of python would tell me that the for loop finishes without a
problem if there are no elements in it.
{{try:}}
{{print articlesformovie[0]}}
{{noarticles=0}}
{{except:}}
{{noarticles=1}}

you're overcomplicating a small issue
{{if articles and len(articles)0:}}
display whatever you want in a for loop
{{else:}}
display your static message
{{pass}}

OK it obviously has nothing to do with the for loop in try except because
the for loop finishes when there are no entries in articles. But some basic
understanding of python should have told me the solution^^
thats what works if anyone is interested:
{{try:}}
{{print article[0].title}}
len(articles) is not necessary
{{if articles:}}
display whatever you want in a for loop
{{else:}}
display your static message
{{pass}}

uhm, depends if he uses lists and articles is = [], there will be a
problem.
Anyway, under some circumstances you're right.

What problem? An empty list evaluates to False.

I am astonished... I missed this in almost 3 years of python development :D
I genuinely repent and knee before you, Anthony
