It's technically list comprehension. Sort of a one-line list transform 
tool.


I recommend reading through some of Dive Into Python 
(http://diveintopython.org/) for lots more cool hands-on tips on Python 
programming. Chapter 3 for a good overview of the uses of Python's 
different data types.


Good advice.

Thanks for your help AJ
I get this:

Error Type: SyntaxError
Error Value: invalid syntax (line 1)

dtml-tree branches_expr=[o for o in
objectValues(['Folder'] if hasattr('orderInt'))]
sort=orderInt skip_unauthorized


I think that Andreas meant

dtml-tree branches_expr=[o for o in objectValues(['Folder']) if 
hasattr(o,'orderInt')] sort=orderInt skip_unauthorized
