[issue3214] Suggest change to glossary explanation: "Duck Typing"

Georg Brandl report at bugs.python.org
Tue Jul 1 22:35:49 CEST 2008


Georg Brandl <georg at python.org> added the comment:

Paddy: IMO hasattr() is the "if it quacks like a duck" part of
duck-typing. It e.g. allows testing "hasattr(x, 'write')" to see if it's
a writable file-like object, and doing something else otherwise.

Benjamin: ABCs are not duck-typing since they involve isinstance() anyway.

----------
resolution:  -> works for me
status: open -> pending
