The key here is that this sort of logic _can_ be accomplished but it's
done by pushing the logic itself into Python code that's related to
the template - filters and tags. There's a lot of built-in ones
(http://www.djangoproject.com/documentation/templates/) and you can
accomplish both of your examples by applying included template filters
like so:
{% for x in y %}
{{ x }}{% if not forloop.last %},{% endif %}
{% endfor %}
Of course, if you're familiar with Python at all you might recall the
string join method; that's here too and is used for exactly this
purpose. So you can actually do:
{{ y|join:"," }}
As for truncating a string, you could use slice as previously noted:
{{ y|slice:":100" }}...
Basically, you just need to become familiar with the tools available -
there's a lot that can be done with them. If you find a need for
something the builtins don't accomplish by themselves or jointly, you
can easily write your own. Again, the idea being to push non-simple or
non-presentation-oriented logic into Python code that *doesn't* live
in the template - separating the layers, as it were. There's plenty of
documentation on it on the site and on blogs and here on the list as
well, if you ever get stuck :)
