The Python tutorial may help with things like embedding quotes and "casting"

(Python is dynamically typed: casting is a foreign concept). http://www.python.org/doc

OK, but not quite so in Zope. For instance, when I want to compare a date to, say, January 1, 1980, I can't just use <=. I must first use the (undocumented) _.DateTime to convert '1980/01/01' to a Date object. THEN I can use <=.

This is the same in Python. Python does not 'type' objects but objects still have a type. You are expected to understand at each stage in the life of an object what type it is.

Incidentally, how can I overload <= to work with my own objects?

Your object must define an __cmp__ method: http://www.python.org/doc/current/ref/customization.html#l2h-130 -Michel
