Description of problem:
I'm working on a package that uses python-iso8601.  This package supposedly works under both python2 and python3, so I would like to make both packages, but there is no python3-iso8601.

It appears that the python-iso8601 upstream has not been active for a few years.  The bug reports are piling up.  Some people have noticed, which is why this fork exists: https://github.com/OpenLearningNet/pyiso8601.  It fixes a few bugs, so it may be worth switching upstreams.  Sadly, the fork doesn't provide python3 support, either.

Issue 23 for the current googlecode upstream has one appraoch.  The package I am working on actually bundles pyiso8601, and takes a simpler approach.  It adds "import sys" at the top, then this a little further down:

if sys.version_info < (3, 0):
    bytes = str

and then does this:

+    if not isinstance(datestring, bytes):
+        raise ParseError("Expecting bytes %r" % datestring)
     m = ISO8601_REGEX.match(datestring)
     if not m:
         raise ParseError("Unable to parse date string %r" % datestring)
