Of course. But I just write some stuff to get my grip on Python again,
haven't used it for a long time. I grabbed the newest version of
"Learning Python" and started to play around. I wanted to use Jinja
because it's a lot like Django (which I'm looking forward to use as
soon as i finished the Python book) but can be used standalone without
any hassle (just easy_install and import).

If the tag is set in the YAML file, it should be written. I guess it
makes no sense to write empty tags... but it does no harm either (or
does it?). So I just check for all allowed tags and if they are set,
they are written, wether or not they are empty.

I do: print tmpl.render({"playlist": playlist})
Well playlist is a dictionary containing the tag-value pairs, parsed
from the corresponding YAML file. In the template i want to itterate
over a list of allowed tags and if the tag is present in the context,
print it. What would be the best way to do this with Djangos template
system?
I just scribbled together something in Jinja because i want to play
around and ended up with this (probably messy stuff):
{%- for tag in ['title', 'creator', 'annotation', 'info', 'image',
'location', 'identifier', 'date', 'license', 'attribution'] %}
{%- if tag in playlist %}
<{{ tag }}>{{ playlist[tag] }}</{{ tag }}>
{%- endif %}
{%- endfor %}
Because i found no way, how i could access the variables from the
template (well locals() shows them, dir() too, but i could'nt access
them) i wrapped them in a second dict with "playlist": playlist, so i
could do "if tag in playlist" and "playlist[tag]".
