Method 1: Installing Python Using DNF Package Manager
The DNF (Dandified YUM) package manager provides the most straightforward approach to installing Python on AlmaLinux 10. This method leverages pre-compiled packages from official repositories, ensuring compatibility and easy maintenance.
Updating the System
Begin by updating your AlmaLinux 10 system to ensure you have the latest security patches and package information. Execute the following commands in your terminal:
sudo dnf clean all
sudo dnf update -yThe system update process may take several minutes depending on your current package versions and internet connection speed. Once completed, enable the EPEL (Extra Packages for Enterprise Linux) repository to access additional Python packages:
sudo dnf install epel-release -yInstall essential development tools that will be useful for Python development and package compilation:
sudo dnf groupinstall "Development Tools" -y
sudo dnf install gcc openssl-devel bzip2-devel libffi-devel zlib-devel wget make -yInstalling Python from Official Repositories
AlmaLinux 10 repositories typically include multiple Python versions to accommodate different project requirements. Check available Python packages using:
sudo dnf list available | grep python3Install the default Python 3 version along with essential development packages:
sudo dnf install python3 python3-devel python3-pip -yThis command installs Python 3, development headers, and the pip package manager simultaneously. The installation process automatically handles dependencies and ensures all components work together seamlessly.
Verify the installation by checking the Python version:
python3 --version
pip3 --versionManaging Multiple Python Versions
For projects requiring specific Python versions, install additional versions using DNF. AlmaLinux 10 repositories may include Python 3.9, 3.10, 3.11, and potentially newer versions:
sudo dnf install python3.10 python3.11 -yUse the alternatives system to manage multiple Python versions and set a default:
sudo alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 1
sudo alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 2
sudo alternatives --config python3This approach allows you to switch between Python versions system-wide while maintaining individual version access through specific commands like python3.10 or python3.11.
Method 2: Installing Python from Source Code
Compiling Python from source code provides maximum flexibility and access to the latest features, optimizations, and security patches. This method is particularly valuable when you need cutting-edge Python versions or specific compilation flags.
Installing Build Dependencies
Source code compilation requires a comprehensive set of development tools and libraries. Install all necessary dependencies before proceeding:
sudo dnf install wget yum-utils make gcc openssl-devel bzip2-devel libffi-devel zlib-devel sqlite-devel readline-devel tk-devel gdbm-devel xz-devel -yThese packages provide essential compilation tools, SSL support, compression libraries, and database connectivity options. The comprehensive dependency installation ensures your compiled Python will have full functionality.
Verify that GCC is properly installed and accessible:
gcc --version
make --versionDownloading Python Source Code
Navigate to your preferred download directory and obtain the latest Python source code. Create a dedicated directory for the installation:
cd /opt
sudo mkdir python-source && cd python-sourceDownload Python 3.13.3 (or the latest stable version) from the official Python website:
sudo wget https://www.python.org/ftp/python/3.13.3/Python-3.13.3.tgzVerify the download integrity by checking the file size and optionally downloading the corresponding checksum file from the Python website. Extract the downloaded archive:
sudo tar -xzf Python-3.13.3.tgz
cd Python-3.13.3Compiling and Installing Python
Configure the build process with optimization flags for enhanced performance. The configuration step prepares the build environment and checks for required dependencies:
sudo ./configure --enable-optimizations --with-system-ffi --with-computed-gotos --enable-loadable-sqlite-extensionsThe --enable-optimizations flag enables Profile Guided Optimization (PGO), which can improve Python performance by 10-20% but increases compilation time significantly. The --with-system-ffi option uses the system’s libffi library for better integration.
Determine the number of CPU cores for parallel compilation:
nprocCompile Python using all available CPU cores to speed up the process:
sudo make -j $(nproc)The compilation process typically takes 15-30 minutes depending on your system specifications. Monitor the process for any error messages that might indicate missing dependencies or configuration issues.
Install the compiled Python using altinstall to avoid overwriting the system Python:
sudo make altinstallThe altinstall option installs Python with version-specific names (e.g., python3.13) while preserving the system’s default Python installation.
Post-Installation Configuration
Create symbolic links for easier access to your compiled Python version:
sudo ln -sf /usr/local/bin/python3.13 /usr/local/bin/python3-custom
sudo ln -sf /usr/local/bin/pip3.13 /usr/local/bin/pip3-customUpdate your PATH environment variable to prioritize your custom Python installation by adding the following line to your ~/.bashrc file:
export PATH="/usr/local/bin:$PATH"Reload your shell configuration:
source ~/.bashrcInstalling Python Package Manager (pip)
The pip package manager is essential for installing and managing Python packages from the Python Package Index (PyPI) and other repositories. Modern Python installations typically include pip automatically, but understanding its configuration and usage is crucial.
Verify pip installation for your Python versions:
python3 -m pip --version
python3.13 -m pip --versionIf pip is missing from any Python installation, install it manually using the get-pip.py script:
wget https://bootstrap.pypa.io/get-pip.py
python3.13 get-pip.py --userUpgrade pip to the latest version for all Python installations:
python3 -m pip install --upgrade pip
python3.13 -m pip install --upgrade pipConfigure pip for enterprise environments by creating a pip configuration file at ~/.pip/pip.conf:
[global]
index-url = https://pypi.org/simple/
trusted-host = pypi.org
timeout = 60Install essential Python packages commonly used in development environments:
python3 -m pip install virtualenv requests numpy pandas matplotlibCreating and Managing Virtual Environments
Virtual environments provide isolated Python spaces that prevent package conflicts and enable project-specific dependency management. This practice is considered essential for Python development workflows.
Understanding Virtual Environments
Virtual environments solve the common problem of dependency conflicts between different Python projects. Each virtual environment maintains its own package installation directory, allowing projects to use different versions of the same package without interference.
Creating isolated environments becomes particularly important when working with multiple projects that require different package versions or when testing code against various dependency combinations. Virtual environments also prevent accidentally modifying system-wide Python packages that might break system tools.
Creating Virtual Environments
Use the venv module (included with Python 3.3+) to create virtual environments:
python3 -m venv myproject-envFor source-compiled Python versions, specify the full path:
/usr/local/bin/python3.13 -m venv myproject-env-313Create virtual environments in a dedicated directory for better organization:
mkdir ~/venvs
cd ~/venvs
python3 -m venv development
python3 -m venv testing
python3 -m venv productionManaging Virtual Environments
Activate a virtual environment to begin using it:
source ~/venvs/development/bin/activateOnce activated, your command prompt will change to indicate the active environment. Install packages specific to this environment:
(development) $ pip install django flask requestsCreate a requirements.txt file to document project dependencies:
(development) $ pip freeze > requirements.txtDeactivate the virtual environment when finished:
(development) $ deactivateRemove virtual environments by simply deleting their directories:
rm -rf ~/venvs/old-projectInstalling Specific Python Versions
Different projects often require specific Python versions for compatibility reasons. This section covers installing and managing multiple Python versions on AlmaLinux 10.
