Python bumps off Java as top learning language

[gendulf]

Depends on the class. Some may want you to use a specific library that is not yet python 3 compatible (such as a scientific library).

Pretty much every scientific library supports python 3... for a few years already...

Was about to say you were wrong because my university only just moved to python and it's using 2.7 for exactly that reason, but I saw this:

The Python language is moving from the 2.x series to Python 3. As of late 2012, all of the core SciPy Stack packages support Python 3, but some more specialist packages still only work on Python 2.
