python-decorators

A dive into the syntax

Orders do matter

When multiple decorators are applied, the order of them does matter.

@a
@b
def f():
    pass

would mean

f = a(b(f))

whereas

@b
@a
def f():
    pass

would mean

f = b(a(f))

Sometimes the end results would be interchangeable, but there are also cases where decorators must be applied in a specific order, so it is important to remember that they are different.
