Barry actually noticed that it's not an empty string as I had assumed, it's the string "[]".
So it looks like the new version of python now sets the default value to type(default) which in this case would be str([]) explaining that value. It's still different from what we'd get with earlier versions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1048710 Title: Regression in argparse for both python2.7 and python3.2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1048710/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
