>>> [1,2] += [2,3] SyntaxError: augmented assign to list not possible A similar error message is generated when augmented assignment is used on tuple literals. This error message is desceptive because augmented assignment is allowed on both of those types. I would change the message to: SyntaxError: can't assign to literal I may generate a patch for this, but not anytime soon.

Logged In: YES user_id=33168 Jeremy, do you agree? How about adding the word literal to the error msg, so it reads: * augmented assign to literal list not possible

Logged In: YES user_id=357491 I like Neal's suggestion.

Logged In: YES user_id=33168 Checked in Python/compile.c 2.289 to add the word literal Hopefully this is clearer. This change could be backported, if anyone cares.
