You can’t install Python 3.9 from the standard Debian 10 repositories. However, you can install it from the python source.
This tutorial will cover the installation procedure Python 3.9 on the Linux system Debian 10 through the command line. All commands we will implement in the Debian 10 Terminal application. Therefore.

Python installation is a very straightforward and relatively simple process that you can complete in a few minutes by following the below-mentioned steps:
Step 1: Installing necessary packages or dependencies
First, you need to install all packages and dependencies required to build the python source. Therefore, to install all the required packages, type the below-mentioned command:
libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev zlib1g-dev
Step 2: Download Python Release
In this step, you will download the latest python release from the python download page. To do this, use the ‘curl’ or ‘wget’ command to download the python release.

Now, by executing the following command, run the below-mentioned configuration script to prepare your system for python source code compilation:
The above script will perform several checks to ensure that all of the dependencies are installed on your system. The ‘–enable-optimizations’ is used here to optimize the Python binary by executing many tests.
Step 5: Install python
Now, start the build process by running the below-mentioned command:
You will modify -j according to your processor’s cores. To find the number by typing the ‘nproc’ command.
Once the above build process is completed, run the following command to install python binaries on your system:
