Question

I know it’s a simple question, but I have strange behaviour in here.

<pre>
          %for key in tags_photo:
          %   try:
                {{ key }} :  {{ exif[tags_photo[key]].raw_value }}
          %   except KeyError:
          %        continue
          %end
</pre>

I assume that only content in pre tag should be repeated like in jinja2..?
But now I got a loop of the whole template..(i mean pre tags repeated also) why??

how to do properly loops in bottlepy template?

Answer 1

You need to close all of your blocks:

<pre>
%for key in tags_photo:
    %try:
        {{ key }} :  {{ exif[tags_photo[key]].raw_value }}
    %except KeyError:
        %continue
    %end
%end
</pre>

(In the code you posted in the OP, the one %end was only closing the try/except block, so the for block was extending to the end of the template.)
