Not quite true; Python requires explicit declaration of names when
they're bound to, but is quite happy to do a scope search (local,
nonlocal, global, builtin) for references. But the rules are fairly
simple. Aside from the possibility that someone imports your module
and sets module.len to shadow a builtin, everything can be worked out
lexically by looking for the assignments.
