Installing Python 3.11 in Debian 11

Updating the apt cache index is the first step in installing Python 3.11 in our Debian 11 system. To accomplish this, issue the below given command:

sudo apt update

Type the following command if there are any packages that need to be upgraded:

sudo apt upgrade

However, as you can see, all the packages in my instance are up to current, so it wasn't necessary.

We've upgraded our system successfully; let's restart it with the following command:

sudo reboot

The process of installing Python 3.11 will now be initiated. We need to install the dependent packages in order to achieve this. Use the command as follows:

sudo apt install wget software-properties-common build-essential libnss3-dev zlib1g-dev libgdbm-dev libncurses5-dev   libssl-dev libffi-dev libreadline-dev libsqlite3-dev libbz2-dev

The following step is to go to the official Python website and download version 3.11 from there. It can be found through the subsequent link:

After that, enter the following command while changing the version:


After that, we have to extract the downloaded file. It can be extracted using the command below:

tar xvf Python-3.11.4.tgz

Let's switch to the working directory after the downloaded file has been successfully extracted. It's for making a Python folder. First, we use the command below to change the directory:

cd Python-3.11.4

We shall then execute the configuration command. In order to accomplish this, enter the following command into your terminal:

./configure --enable-optimizations

The Python build procedure will now be started as the following step. In order to accomplish this, enter the following command into your Terminal:

sudo make altinstall

After running the above-mentioned command, your output should appear as follows if Python was successfully installed:

At the end of the output from that previous command, you will see the following message:

Type the next command to check the installation:

python3.11 --version

The following link allows us to install the Python modules as well:

Click the aforementioned link, then use the following command to install any desired modules:

python3.11 -m pip install <moduleName>

Since everything is finished now, let's just use Python 3.11. The following command should be used to use the Python 3.11 shell:


We will now create our first Python 3.11 program in Debian 11. Everyone is aware of the first program a programmer ever wrote, which printed "Hello World." Just print "hello world" for now.  Fill in the following:

>>> print("Hello World!")

Type the following command to end or quit the Python shell session:

>>> exit()
