This plugin adds Python completions and some IDE-like functions to Sublime Text 3, through the use of the Rope library. It is a complete rewrite of SublimeRope for ST2. It should be a lot faster and easier to use than SublimeRope was. In contrast to SublimeRope, it does use the built in Python only for UI-related functions, the completions and refactorings are calculated using the exact same python interpreter you use for your project (e.g. the one in your virtualenv). This eliminates a lot of small and big problems that SublimeRope had, e.g., not recognizing dict comprehensions because Python2.6 is used in ST2, or not recognizing some of your libraries because you did not configure all the paths etc.. Everything your projects interpreter sees, should be visible to SublimePython -> easier configuration.
