Hardly any changes at all, and the things that did change didn't actually make a clear difference in productivity or the clarity of your code. The ability to make breaking changes wasn't really used to improve the language, maybe except for unicode handling – no new syntax (would've loved functions-as-blocks myself), no getting rid of old crufty syntax, nada.

> things that did change didn't actually make a clear difference in [...] the clarity of your code print "%s remember to %s in %s if %s but never %s" % (some_random_tuple) vs print("{when} remember {what} in {room} if {condition} but never {dont}".format(* * dict_with_explicit_keys)) A bit verbose but much clearer and future-proof.

  But you can already do that in Python 2.7.

  That's an unfair comparison, however, print "%(when)s remember to %(what)s in %(room)s but never %(dont)s" % dict_with_explicit_keys was supported back in at least 2.4.

  Python 2.7 supports string.format and Python 3 supports % formatting. The only actual difference in that example is that print became a function in Python 3, requiring some additional parentheses. (Something that can be mechanically translated without much hassle.)

    Wasn't the % formatting missing from early versions of python3?
