NameError: global name 'basestring' is not defined (python 3)

[minami-o]

Hey there,
Nice work you have done, thanks!
I just came across an error while trying to download/upload files with my python3.3 install:

NameError: global name 'basestring' is not defined

After a quick web research, I found the solution mentioned here to work just fine.
I added the lines right after the import lines in client.py.

I also would really like to use you library with Python3. As @minami-o mentioned, adding

try:
    basestring
except NameError:
    basestring = str

after all the imports should be sufficient.

The solution in pull request #28 should also work.

Same problem here. Could you possibly do a new release, please?

In python 3 just add basestring = str
