How to install Python 3.6.1 in Ubuntu 16.04. Python 3.6.1 is now the latest maintenance release of Python 3.6 and supersedes 3.6.0. Python is a widely used high-level programming language for general-purpose programming.
Python 3.6 series comes with new syntax features, such as:
- PEP 498, formatted string literals.
- PEP 515, underscores in numeric literals.
- PEP 526, syntax for variable annotations.
- PEP 525, asynchronous generators.
- PEP 530: asynchronous comprehensions.
Significant improvements in the standard library:
- The asyncio module has received new features, significant usability and performance improvements, and a fair amount of bug fixes. Starting with Python 3.6 the asyncio module is no longer provisional and its API is considered stable.
- A new file system path protocol has been implemented to support path-like objects. All standard library functions operating on paths have been updated to work with the new protocol.
- The datetime module has gained support for Local Time Disambiguation.
- The typing module received a number of improvements.
- The tracemalloc module has been significantly reworked and is now used to provide better output for ResourceWarning as well as provide better diagnostics for memory allocation errors. See the PYTHONMALLOC section for more information.

Please note that after installing Python 3.6, you will have to direct the system to use python 3.6 instead of the default 3.5:
sudo apt-get update
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2
