Upstream branches should now have the proper fixes for this issue. There may be some follow-on doc clarifications but others, but functionally, you should be good to go.

This seems related, might even be the same, but fails with a different
case/error message:
#-- begin code--
import argparse
import sys
parser = argparse.ArgumentParser()
parser.add_argument(--log-file, -l, default=sys.stderr,
type=argparse.FileType('a'))
args = parser.parse_args()
#-- end code--
$ python bin/test-broken.py
usage: test-broken.py [-h] [--log-file LOG_FILE]
test-broken.py: error: argument --log-file/-l: invalid FileType('a') value:
open file 'stderr', mode 'w' at 0x7f201a0fc270

[Bug 1048710] [NEW] Regression in argparse for both python2.7 and python3.2
Public bug reported: Using the following example: --- #!/usr/bin/python import argparse parser = argparse.ArgumentParser() parser.add_argument(--test, dest=test, type=str, default=[], action='append') args = parser.parse_args() args.test.append(something) --- Then running it with simply python test.py (WITHOUT passing --test), you get the following: Traceback (most recent call last): File test.py, line 11, in module args.test.append(something) AttributeError: 'str' object has no attribute 'append' My understanding of argparse is that when using both default=[] and action=append, args.test should always be a list, empty if not passing --test or a list containing the --test values if passed. After the recent update, it seems to instead default to an empty string. This must somehow be related to the type field as for some reason, removing type=str fixes the issue though I don't really see why and it's still a clear regression. ** Affects: ubuntu Importance: Undecided Status: New -- 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
[Bug 1048710] Re: Regression in argparse for both python2.7 and python3.2
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

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode. To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1048710/+editstatus and add the package name in the text box next to the word Package.
