Duck typing is an aspect of it being dynamically typed, not whether it is strong/weak. But strong/weak is not formally defined, so if duck typing disqualifies it for you, so be it.

I always think of Python as having "fairly strong" typing, because you can override the type of objects by just assigning to __class__.
