PEP 3104 says: """ A shorthand form is also permitted, in which nonlocal is prepended to an assignment or augmented assignment:
nonlocal x = 3 The above has exactly the same meaning as nonlocal x; x = 3. (Guido supports a similar form of the global statement [24].) """ The PEP metadata says it was approved and implemented in 3.0, yet this part never seems to have been implemented: Python 3.7.0a3+ (heads/master:53f9135667, Dec 29 2017, 19:08:19) [GCC 7.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> def f(): ... x = 1 ... def g(): ... nonlocal x = 2 File "<stdin>", line 4 nonlocal x = 2 ^ SyntaxError: invalid syntax Was this just an oversight, or did it get rejected at some point and no-one remembered to update that PEP? -n -- Nathaniel J.
