The example Andrew presented is certainly the Albatross way, but you
could also do things like this with Andrew's improved template parser
in 0.06 (if you were so inclined):

- - reptile.html - - - - - - - - - - - - - - - - - - - - - - - - - -
<html>
<al-exec expr='
print "<ul>"
for reptile in ["Crocodile", "Python", "Iguana", "Tortoise"]:
    print "<li> %s </li>" % reptile
print "</ul>"
'>
</html>
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

The example program adds a write() method to the execution context to
make it look like a file for the print statement.

- - reptile.py - - - - - - - - - - - - - - - - - - - - - - - - - - -
#!/usr/bin/python
import sys
import albatross

class Ctx(albatross.SimpleContext):
    def write(self, data):
        self.write_content(data)

ctx = Ctx('.')
ctx.locals.reptiles = ["Crocodile", "Python", "Iguana", "Tortoise"]
template = ctx.load_template("reptiles.html")

old_stdout = sys.stdout
try:
    sys.stdout = ctx
    template.to_html(ctx)
finally:
    sys.stdout = old_stdout

print "Content-Type: text/html"
print
ctx.flush_content()
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Produces the following output...

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Content-Type: text/html

<html>
<ul>
<li> Crocodile </li>
<li> Python </li>
<li> Iguana </li>
<li> Tortoise </li>
</ul>
</html>
