Why does python print version info to stderr?

by

Python 3.4 was modified to output to stdout, which is the expected behavior. This is listed as a bug with Python here: http://bugs.python.org/issue18338. The comments on the bug report indicate that while stdout is the reasonable choice, it would break backward compatibility. Python 2.7.9 is largely unchanged, because so much relies on it.

Hope that helps!
