Twine have indirect Python 2 only dependency.

Twine rely on clint which install args, which AFAICT has no published Python 3 compatible versions:

  File "/root/miniconda3/lib/python3.6/site-packages/args.py", line 394, in <module>
    flags = args.flags
  File "/root/miniconda3/lib/python3.6/site-packages/args.py", line 328, in flags
    return self.start_with('-')
  File "/root/miniconda3/lib/python3.6/site-packages/args.py", line 192, in start_with
    if _is_collection(x):
  File "/root/miniconda3/lib/python3.6/site-packages/args.py", line 37, in _is_collection
    if isinstance(obj, basestring):
NameError: name 'basestring' is not defined

Which has the side effect of breaking as soon as sphinx autolink kick in and try to figure out what blah blah `args` blah blah could mean as it import args. (numpy/numpy#9005)

It would be nice to have twine be completely Python 3 compatible.

The activity on Clint and Args make me doubt I'll get a response though, so opening issue here.

It seems like clint is only being used to generate a progress bar. Perhaps we could use tqdm (which is active and supports Python 3) instead?

I'd merge a pull request that switches us over to tqdm. Thanks for pointing this out @Carreau. :)

See #242.

Thanks to you for maintaining twine, and being responsive !
