How to Install Python 3.8 on Debian 10
3 min read
Python is one of the most widely used programming languages in the world. With its simple and easy to learn syntax, Python is a popular choice for beginners and experienced developers. Python is quite a versatile programming language. It can be used to build all kinds of applications, from simple scrips to sophisticated machine learning algorithms.
Debian 10 includes Python version 3.7, which can be installed or updated using the
At the time of writing, Python 3.8 is the latest major release of the Python language. It includes many new features such as assignment expressions, positional-only parameters, f-strings support, and more. Python 3.8 is not available in the standard Debian 10 repositories.
This tutorial covers how to install Python 3.8 on Debian 10. We’ll also show you how to create a virtual environment.
Installing Python 3.8 on Debian 10
Building Python 3.8 on Debian is a relatively straightforward process and will only take a few minutes.
Start by installing the packages necessary to build Python source:
sudo apt update
sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev curl libbz2-dev
curl -O https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tar.xz
When the download is complete, extract the tarball:
tar -xf Python-3.8.2.tar.xz
Navigate to the Python source directory and run the
The script performs a number of checks to make sure all of the dependencies on your system are present. The
--enable-optimizationsoption will optimize the Python binary by running multiple tests, which will make the build process slower.
maketo start the build process:
make -j 4
-jto correspond to the number of cores in your processor. You can find the number by typing
Once the build is done, install the Python binaries by running the following command as a user with sudo access:
sudo make altinstall
Do not use the standard
make installas it will overwrite the default system
At this point, Python 3.8 is installed on your Debian system and ready to be used. You can verify it by typing:
Creating a Virtual Environment
Python virtual environment is a self-contained directory tree that includes a Python installation and a number of additional packages. It allows you to install Python modules in an isolated location for a specific project, rather than being installed globally. This way, you do not have to worry about affecting other Python projects.
In this example, we’ll create a new Python 3.8 project called
my_app inside the user home directory.
First, create the project directory and switch to it:
mkdir ~/my_app && cd ~/my_app
From inside the project root run the following command to create a virtual environment named
python3.8 -m venv my_app_venv
Activate the environment:
Once activated, the shell prompt will be prefixed with the name of the environment. Starting with Python 3.4, when creating virtual environments pip, the package manager for Python is installed by default.
Within the virtual environment, you can use
pip instead of
python instead of
Once you are done with your work to deactivate the environment, type
deactivate, and you will return to your normal shell.
We have shown you how to install Python 3.8 on Debian 10. You can now create a virtual environment and start developing your Python 3 projects.
