I can't claim a comprehensive familiarity with Python template
offerings, but all of the packages approved for use at my previous
workplace left me cold. The most popular were ClearSilver and Django,
and both felt horribly limiting compared to the Template Toolkit,
which I became acquainted with when hacking on Bugzilla some years
ago. Neither supports what I would consider very basic operations on
the template data. Nothing like the following can be expressed in
those packages:
from pprint import PrettyPrinter
from template import Template
print Template().processString(
"the list is [% a.pformat(b(c + d)) %]",
{ "a": PrettyPrinter(2, 40), "b": range, "c": 10, "d": 20 }
)
Here we have a template that includes a method call, a function call,
and simple addition. Neither Django nor ClearSilver can manage any of
these three things. Both of those packages offer other features not
found in the Template Toolkit; it was the relative impotence of the
templating systems that drove me to attack the translation.

The online documentation, yes. All source-level documentation (from
which the online documentation is largely drawn) has been converted
into Python docstrings in the source code. They can be read by
browsing the Subversion repository or by importing the code and using
help(); eg:
>>> import template.stash
>>> help(template.stash)
... module docs ...
>>> help(template.stash.Stash)
... class docs ...
>>> help(template.stash.Stash.get)
... method docs ...
