This talk will go over how the simple
from sys import version turns out to be slightly complicated. The details of imports -- from how the import statement is interpreted to deciding what object to return -- will be discussed. While the talk will discuss things from the perspective of Python 3.3 (and thus importlib), the overall semantics will (mostly) apply to older versions of Python.
In this talk I will try to convince you that Python 3.3 is superior to Python 2.7 by going over the differences between Python 2.7 and Python 3.3 along with benchmark information to show where Python 3.3 shines in comparison to Python 2.7 (and vice-versa). If I accomplish my goal, you will walk out of this talk convinced that Python 2.7 is not the final version of Python you want to support.
