Which brings up a question. I finally settled on Python 2.7 for various reasons, but find some 3.3 things useful. Generators are one-off and input is one-off, so they match well for testing, for instance.
I don't understand that last sentence.
I checked the docs and I don't see many __future__ imports. Are these all there are, or are there other useful ones that are better hidden?
Try this one: from __future__ import braces
- nested_scopes, generators, division, absolute_import, with_statement print_function unicode_literals
As of Python 3.3, the full list of __future__ imports are: py> import __future__ py> __future__.all_feature_names ['nested_scopes', 'generators', 'division', 'absolute_import', 'with_statement', 'print_function', 'unicode_literals', 'barry_as_FLUFL'] __future__ features will never be removed, even when they no longer have an effect. For example, nested scopes have become standard since Python 2.2, but "from __future__ import nested_scopes" will be legal (and a no-op) so long as Python exists. There may be new __future__ features in the future. For example, I wouldn't be surprised if Python 3.5 or 3.6 introduces "from __future__ import decimal_literals" or some such thing.
I'm not importing them all, just what seems useful to me at this point, and renaming raw_input, so my 2.7 is kind of 3.3ish. But is there anything I missed or any problems I'm unaware of in what will be my standard header, below? #Using Python 2.7 on Win 7 from __future__ import generators, division, with_statement, print_function import sys if int(sys.version[0]) < 3: input = raw_input
You don't need generators in 2.7, they have been standard since Python 2.4. -- Steven _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
