What would people think about adding sys to __builtins__ so that
"import sys" is no longer necessary? This is something I must add to
every script I write that's not a one-liner since they have this idiom
at the bottom:
if __name__ == "__main__":
Additionally, the necessity of "import sys" makes some one-liners a
little more unwieldy than they should be--it is surely the module I am
missing the most in one-liners. For example, with this proposal, this
$ python -c "import sys; print ''.join(sorted(sys.stdin.readlines()))"
could be replaced by:
$ python -c "print ''.join(sorted(sys.stdin.readlines()))"
Since sys is surely the most commonly used module (it is imported in 108
of 188 Python 2.4 stdlib modules on my system, and certainly more than
any other module), I would hope few people would be affected by a
Other languages (e.g. C#) always make their system namespace available
without needing a special import.
In short, given the wide use of sys, its unambiguous nature, and the
fact that it really is built-in already, although not exposed as such, I
think we would be better off if sys were always allowed even without an
