Ln -s /usr/local/bin/ python3.It would be wise to use pyenv to safely manage multiple versions of Python installed on the same system. To set your installed python as default, run the below commands one by one (You may change python3.3 to python3.4 in the code): rm /usr/local/bin/python

Or install python 3.4.0 via: sudo apt-get update sudo apt-get install python3.4 Install Python 3.3.5 via: sudo apt-get update sudo apt-get install python3.3 You may read the PPA description in the output and then: To add the PPA, press Ctrl+Alt+T on keyboard to open the terminal and run: sudo add-apt-repository ppa:fkrull/deadsnakes The two Python releases are available in the PPA for Ubuntu 14.04 and Ubuntu 12.04. a new “asyncio” module, a new framework for asynchronous I/OĪ third party launchpad PPA contains older and newer Python version for Ubuntu.a new and improved protocol for pickled objects.a new hash algorithm for Python strings and binary data.a new “tracemalloc” module for tracing Python memory allocations.a bundled installer for the pip package manager.standardizing module metadata for Python’s module import system.changing file descriptors to not be inherited by default in subprocesses.a new C API for implementing custom memory allocators.adding single-dispatch generic functions to the standard library.

This quick tutorial is going to show you how to install Python 3.3.5 (or 3.4.0) and set as default in Ubuntu 14.04 and Ubuntu 12.04.
