So, ndg-httpsclient, mrjob, numpy, scrapy, monotonic and possibly others do have python3 compatibility.<p>Then there&#x27;s a bunch of deployment tools like ansible, fabric, and marionette which don&#x27;t really need to be python3 compatible for use.<p>Then there&#x27;s tools like MySQL-python, python-gflags, python-cjson, INITools, filechunkio, which have python3 compatible alternatives, often in the standard library.<p>That brings the total up to 331<p>That leaves basically 3 categories of things left: mozilla tools, database connectors (many of which probably have python3 bindings though I haven&#x27;t looked), and single sign on tools. Those account for 12 of the remaining 29 libraries.<p>That&#x27;s pretty ready.
