How to Install Python 3.11 on Ubuntu / Linux Mint
This tutorial will be helpful for beginners too, on how to install Python on Linux and also shows how to compile and install Python 3.11 on Linux distributions (ie) Ubuntu, Linux Mint, AlmaLinux, Fedora, and Rocky Linux.
What is Python?
Python is a programming language with many features, such as an intuitive syntax, powerful data structures, and robust support for object-oriented programming.
Python is used in a variety of domains, such as web development, scientific computing, and artificial intelligence.
Install Python 3.11 on Ubuntu / Linux Mint
Python can be installed on Linux systems via 2 methods
- Method 1: Via Repository
- Method 2: Via Source file
Method 1: Via Repository
For Debian-based systems
Step 1: Add the DeadSnakes PPA
sudo add-apt-repository ppa:deadsnakes/ppa
Step 2: Update the repository and install Python 3.11
sudo apt install python3.11
Step 3: To verify the installation, open a terminal window and type the following command:
python3 --version
From the above image Python, 3.8 is the default one, If you want to use Python 3.11 as your default Python, then you can type the following commands
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.11 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 2
Step 4: Configure Python 3.11 as the default
sudo update-alternatives --config python3
Method 2: Via Source file
Step 1: Install the required dependencies before proceeding
sudo apt install build-essential libreadline-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev zlib1g-dev
Step 2: Download the Python Source file from the FTP site or use the below command
wget https://www.python.org/ftp/python/3.11.0/Python-3.11.0.tar.xz
Step 3: Extract the contents
tar -xf Python-3.11.0.tar.xz && cd Python-3.11.0 && mv Python-3.11.0/ /opt/
Step 4: Configure Python from the source file
sudo ./configure --prefix=/opt/Python-3.11.0 --enable-optimizations
Step 5: Build and install Python 3.11
sudo make altinstall -j4
From the above command, I have provided j4, you can provide the numbers based on your CPU.
Step 6: Set Python 3.11 as the default
sudo update-alternatives --install /usr/bin/python python /opt/Python-3.11.0/python 1
Uninstall Python 3.11
To uninstall Python 3.11 run the below command
sudo apt remove python3.11
Conclusion
From this tutorial, you have learned how to download and install Python 3.11 on Ubuntu 22.04, 20.04, and Linux Mint 21

Your command prompt will now look slightly different: the command line will be preceded by ow we have set up a virtual environment, which is where any Python libraries we decide to install will be stored. Now that we have installed virtualenv, we can create a Virtual Environment - run this in your command prompt: Save it to your home folder (/Users/your_name). For installing the packages, you have to choose the environment whether it’s global or virtual or conda. To install virtualenv on the Mac, download this file: Since the Deadsnakes PPA has almost every version of Python in its database, you can install older versions of Python as well. Download the latest version of Python from the added PPA: sudo apt install python3. Update your systems package list: sudo apt update. Type "help", "copyright", "credits" or "license" for more information.įor the purposes of this workshop, we will install virtualenv, a useful tool for creating isolated development environments (which makes it easier to experiment with various versions of Python code libraries and modules). sudo add-apt-repository ppa:deadsnakes/ppa.
You should see something like the following:.
Test your install by typing this into the command prompt: python.
Open the Terminal application (under Applications > Utilities) and type into the command prompt: hash -r.
dmg file by double-clicking and follow the onscreen instructions to install Python on your computer.
Download the latest version of Python 2.7 for the Mac from /download/releases/2.7.3.

This from XCode (Macs came bundled with the XCode Developer Tools DVD you can also download a full version from ) or the smaller
Before we begin, make sure you have GCC installed to compile Python.
However, using the pre-installed version of Python for this workshop can pose some problems, so we will be installing the "real" version, straight from.
PYTHON3_NUMPY_INCLUDE_DIRS = /usr/lib/python/dist-packages/numpy/core/include/ Note To specify Python2 versions, you can replace PYTHON3_ with PYTHON2_ in the above parameters.īuild.Macs come pre-installed with a special version of Python. Install the latest version of Python Go to and press the yellow Download Python-button.
PYTHON3_INCLUDE_DIR = /usr/include/python.
Double-click the downloaded file to extract the archived contents. First, you need to download Visual Studio Code for macOS from its official website at 2.
set BUILD_EXAMPLES=ON to build all examples In this part of the tutorial, we’re going to install Visual Studio Code for Python development on macOS.
set BUILD_DOCS=ON for building documents (doxygen is required).
to build with modules from opencv_contrib set OPENCV_EXTRA_MODULES_PATH to /modules.
build type: CMAKE_BUILD_TYPE=Release (or Debug).
set the binary build path to your CMake build directory, e.g.

Step 3: Upgrade your pip with the latest version to avoid errors during the installation. Step 2: Now check if pip3 and python3 are successfully installed in your system. Follow the below steps to install the PyQt package on macOS using pip: Step 1: Install the latest version of Python3 in macOS.
set the OpenCV source code path to, e.g. Method 1: Using pip to install PyQt Package.

Find the version for your system and download CMake from their release's page.
If you XCode and XCode Command Line-Tools installed, you already have git installed on your machine. Note OSX comes with Python 2.7 by default, you will need to install Python 3.8 if you want to use it specifically. This tutorial will assume you have Python, Numpy and Git installed on your machine.
Python 2.7 or later and Numpy 1.5 or later.
The following steps have been tested for MacOSX (Mavericks) but should work with other versions as well. Next Tutorial: Cross compilation for ARM based Linux systems Prev Tutorial: Use OpenCL in Android camera preview based CV application
