__future__ frequently appears in Python modules. I do not understand what __future__ is for and how/when to use it even after reading the Python's __future__ doc.
Can anyone explain with examples?
A few answers regarding the basic usage of __future__ I've received seemed correct.
However, I need to understand one more thing regarding how __future__ works:
The most confusing concept for me is how a current python release includes features for future releases, and how a program using a feature from a future release can be be compiled successfully in the current version of Python.
I am guessing that the current release is packaged with potential features for the future. However, the features are available only by using __future__ because they are not the current standard. Let me know if I am right.
