if 'a' is some string, and you want the first three characters:
<!--#var "a[0:3]"-->

or

<!--#var "a[:3]"-->

This is the Python 'slicing operator'. You may want to look up the
Python tutorial at www.python.org; the expressions in the 'var' tags are
Python expressions (with unfortunately a lot of convoluted stuff due to
the _ namespace bits).

Haven't worked with that one myself yet. :)
