Python 3 is the latest major version of Python, a scripting language used by many open source developers.

Python 3 is the latest major version of Python, a scripting language used by many open source developers. Python is especially important to Ubuntu - tools like the Software Center, Update Manager, Apport, Ubiquity (Ubuntu's installer), and many more are written in Python.

Many of the Python programs on an Ubuntu system are actually written in Python 2, as there are substantial differences between the two languages and it is not always worthwhile to translate a program from Python 2 to 3. However, new applications and utilities are being written in Python 3, so it is becoming more and more prominent. Eventually Python 2 will be largely phased out.

It is a release goal for Ubuntu 14.04 LTS to have only Python 3 on the desktop CD images.

Python/3 on Ubuntu wiki (see also this blueprint)

For developers, it's probably a good idea to learn Python 3 (and use it for any new programs), though developers who want to work on existing Python 2 projects will need to know Python 2.

More information on Python can be found at the official site, Wikipedia, and Programming/Python in the Ubuntu help wiki.

How do I install Python 3.6 using apt-get?

I've tried the normal way, sudo apt-get install python3.6, but... well... that didn't work. So, how would I go about it? (I'd preferably not build it on my own) I'm using Ubuntu 16.04.
