[Zope] Truncating strings with DTML

[Peter Bengtsson]

easy:
<dtml-let strDirPath="'/'.join(strDirPath.split('/')[:-1])">
You don't need to use _.string.legacy() functions. Just put your
python expression inside the quotation marks. If you're new to python,
don't let DTML be your place to learn python. Use a nice editor like
IDLE.

PS. Which scripting language did you work with before you came to Zope?
