In python you'd use the range() method, but that method is not available in 
Zope, at least, not in version 1.x. Zope 2 does include a range method, 
it's a member of the _ object. You would use it like this:

<!--#in "_.range(1, cant)"-->

In Zope 1.x, you'll have to create an external method that returns the 
result of the python range method for you:

def MyRange(iMax):
     return range(1, iMax)

and call it from your in tag:

<!--#in "MyRange(iMax=cant)"-->

Note: Above code is untested. YMMV.
