Hi Gustav, This is great! A few quick comments (mostly echo-ing Stephan's).
1. You basically have a NEP already! Making a PR from it allows to give line-by-line comments, so would help! 2. Don't worry about supporting python2 specifics; just try to ensure it doesn't break; I would not say more about it! 3. On `set_printoptions` -- ideally, it will become possible to use this as a context (i.e., `with set_printoption(...)`). It might make sense to have an `override_format` keyword argument to it. 4. Otherwise, my main suggestion is to start small with the more obvious ones, and not worry too much about format validation, but rather about getting the simple ones to work well (e.g., for an object array, just apply the format given; if it doesn't work, it will error out on its own, which is OK). 5. One bit of detail: the "g" one does confuse me. All the best, Marten _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org https://mail.scipy.org/mailman/listinfo/numpy-discussion
