In Python, does the term decorator mean the design pattern as in Design Patterns by GoF, or does it mean something else?

Question

The term decorator appears in Python, and now in Angular2 as well.

In Python, does it mean the decorator design pattern as in the book Design Patterns by GoF, or does it mean something else? (such as something just to annotate, like Java annotation?)

so that's very close to the OOP decorator... just except that OOP decorator are 2 classes, while functional decorator is about 2 functions... both are the same concept that one absorbs the other and providing the exact same interface – nonopolarity Apr 19 '16 at 11:27
Yes, both having similar concept – Hassan Mehmood Apr 19 '16 at 11:30
