Would it be possible to add:

[http://docs.python-requests.org/en/latest/](http://docs.python-requests.org/en/latest/)

to the Slicer distribution. It has an Apache 2.0 license and is a lot easier to use than urllib or urllib2

I agree that it would be useful. This package is Python-only, but it depends on a couple of other packages.

@jcfr What is the recommended process now for adding more Python packages to the Slicer distribution?

Note that you can install `requests` using `pip` as shown in this post: [Slicer-Python Packages Use and Install](https://discourse.slicer.org/t/slicer-python-packages-use-and-install/984/9?u=lassoan). The only limitation is that on Windows you need to start Slicer as an admin, which may not be very user friendly.

We may have a way around that. I will follow up with more details later.

Would that work around allow an extension to load dynamically the python requests package like the above example?

Until @jcfr fixes the installation issue, you can add these packages to your extension. Simply copy the unzipped package into your module directory. See for example the ptvsd module in [https://github.com/SlicerRt/SlicerDebuggingTools/tree/master/PyDevRemoteDebug](https://github.com/SlicerRt/SlicerDebuggingTools/tree/master/PyDevRemoteDebug)
