To me, "batteries included" means that I can:
1) Write a Python script on any Ubuntu laptop that I put my hands on,
and expect it to work.
2) Put a shebang on it, chmod it plus exx, and give it to someone, and
expect it to work on his system.
3) Post it to my web site along with the comment "You will need a
Python interpreter to run this", and expect it to work.
Every third-party library I need weakens that. Sure, situation 1 isn't
too hard; but the other two end up becoming a bit awkward. The
Yosemite Project requires a support module on Windows, making it that
bit harder to share with people; but I accept that, because it's doing
some rather unusual things (simulating keypresses on another window).
Sorting a list is not unusual enough to justify a third-party module.
