Well, just reverse the order of -= in second statement. If you write =-, it will magically work. ;-) But in the general case, sometimes introducing temporary variables is the simplest solution. The alternative would be to implement pointwise -= for tuples, which would be extremely confusing since they already implement += with a completely different semantics. |

If you want to pursue your suggestion for a change in the language, the best place to do so is first on the python-ideas mailing list (https://mail.python.org/mailman3/lists/python-ideas.python.org/). The issue tracker here is more for bugs and minor enhancements. |
