Join For FreeIn this post, we will install Python 3.7.0 on Ubuntu 18.04 / Debian 9.5. This is the latest version of the Python Programming Language.
What's New?
Python 3.7 gives us some new features, including:
- Postponed evaluation of type annotations
- async and await are now reserved keywords
- New contextvars and dataclasses library modules
- New
breakpoint()
function - and more
For more, check out the What's New in Python 3.7 page.
Preparations
Perform all the updates.
apt update && apt upgrade -y
Install everything we will need to build the source for Python.
apt install build-essential -y
apt install libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev -y
If you are on Debian, then you need to install zlib.
apt install zlib1g -y
First, download the source tarball.
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
Unzip the tarball.
tar -xzvf Python-3.7.0.tgz
Next, we need to configure the build.
./configure --enable-optimizations
This will enable a release build of the code.
The downside is that it will take a while to build because it will be running tests that will optimize the binary to run faster.
If you don't care then you can run configure without the -enable-optimizations
flag.
Build Python
Next we need to build the binaries.
make
Once the build is done we can install the binaries.
make install
Python 3.7 is now installed.
# python3
Python 3.7.0 (default, Oct 1 2018, 13:10:35)
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

Create a Virtual Environment
Since Python 3.3, venv
has been included with Python.
To create a virtual environment, use the -m venv
command line option.
$ python3 -m venv ../venv/py37test
Now you can activate the environment with:
$ source ../venv/py37test/bin/activate
You now have a Python 3.7 virtual environment.
(py37test)[email protected]:~/Development/python/py37test$ python --version
Python 3.7.0
The virtual environment is complete with Pip version 10.0.1.
$ pip --version
pip 10.0.1 from /home/bill/Development/python/venv/py37test/lib/python3.7/site-packages/pip (python 3.7)
(py37test)[email protected]:~/Development/python/py37test$
