Hello,

the jinja2 syntax is correct that way, see also this for reference for
variable naming:
http://jinja.pocoo.org/docs/templates/index.html#variables

The invalid syntax is raised when? Can you post the error a bit more
detailed, this will help giving you any advice.

If you know the code part raising the error and you post it, this will
also help.

Agreed. But my guess would be the lack of colon on the for loop...
which would be highlighted by the error thrown.

You might try using your jinja template
with named tuples ....

# -------------------------------------------

from jinja2 import Template

from collections import namedtuple as NT

nt = NT( 'Navigation' , 'href caption' )

n1 = nt( 'http://python.org' , 'python' )
n2 = nt( 'http://cython.org' , 'cython' )
n3 = nt( 'http://jython.org' , 'jython' )
n4 = nt( 'http://pypy.org/' , 'pypy' )

nav = ( n1 , n2 , n3 , n4 )

tmpl = Template( '''\
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html lang="en">
<head>
<title>My Webpage</title>
</head>
<body>
<ul id="navigation">
{% for url , caption in navigation %}
<li><a href="{{ url }}">{{ caption }}</a></li>
{% endfor %}
</ul>

<h1>My Webpage</h1>
{{ a_variable }}
</body>
</html>
''' )

print tmpl.render(
variable = 'Navigation' , navigation = nav )
