New submission from John Hossbach <[email protected]>:
https://docs.python.org/3.5/tutorial/controlflow.html#function-annotations
The end of the first paragraph states, "The following example has a positional
argument, a keyword argument, and the return value annotated:"
However, the only function call is f('spam') which has a single positional
argument.
I believe the author was referencing the output of print("Annotations:",
f.__annotations__) which was:
Annotations: {'ham': <class 'str'>, 'return': <class 'str'>, 'eggs': <class
'str'>}
and then confused that with 4.7.2. Keyword Arguments
(https://docs.python.org/3.5/tutorial/controlflow.html#keyword-arguments) where
it points out that keyword arguments follow positional arguments. However, the
difference between identifying a positional argument vs keyword argument is
done at the function CALL, not the function DEFINITION since any argument can
be both positional or keyword, depending on how it is referenced.
Moreover, the last sentence in 4.7.2. Keyword Arguments, points out that the
order of unsorted sequences is undefined, which would then explain why 'return'
appears in the middle here instead of at the end.
