Not necessarily. Classes that overrides __len__ may fool that assumption
(well, in python classes that overrides special functions may do
anything it is never intended to do).
I often think an "if item:" as "is item workable?". What the exact
definition of "workable" is just something I don't care, at least until
I need to debug the code. A container is workable if it contains
something; most of the time, an empty sequence does not have any value
(pun intended) and thus unworkable.
