This is totally counter to conventional comparisons, and is an excellent example of why the equivalence of ‘3’ to ‘>=3, <4’ is a bad idea. Instead, the default should be ‘==’. That is, ‘Requires-Python: 3’ should be equivalent to ‘Requires-Python: ==3’; and only “3” or “3.0” or “3.0.0” etc. will match. I maintain that is what most people will expect on seeing that syntax. If a less strict range is desired, the existing comparison operators ‘>’, ‘>=’, ‘<’, ‘<=’ are sufficient, more obvious, and more explicit. In other words, to get the meaning you desire above, the existing operators can be used: ‘Requires-Python: >=3, <4’. -- \ “Not using Microsoft products is like being a non-smoker 40 or | `\ 50 years ago: You can choose not to smoke, yourself, but it's | _o__) hard to avoid second-hand smoke.” —Michael Tiemann | Ben Finney _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
