  5. Performance Enhancements: Python 3.10 brings several performance optimizations, leading to faster execution times for certain operations and workloads.

Step 1: Update Your Ubuntu System

Before proceeding with the installation, ensure that your Ubuntu 20.04 system is up-to-date by running the following commands:

sudo apt update
sudo apt upgrade

This will update your package lists and upgrade any existing packages, ensuring a smooth installation process.

Step 2: Add the Deadsnakes PPA

To install the latest version of Python, you’ll need to add the Deadsnakes PPA (Personal Package Archive) to your system. Run the following commands:

sudo apt install software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa

Press Enter when prompted to continue.

Step 3: Install Python 3.10 on Ubuntu

After adding the Deadsnakes PPA, you can now install Python 3.10 by running:

sudo apt install python3.10

This command will install Python 3.10 on Ubuntu along with its associated libraries and tools.

Step 4: Verify the Installation

Once the installation is complete, verify the installed version of Python by running:

python3.10 --version

This should output the version number of the installed Python 3.10.

Step 5: Set Python 3.10 as the Default (Optional)

If you want to set Python 3.10 as the default Python version on your system, follow these steps:

  1. Install the update-alternatives utility:
   sudo apt install update-alternatives
  1. Configure Python 3.10 as the default version:
   sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 1
   sudo update-alternatives --config python3

Choose the entry corresponding to Python 3.10 when prompted.

  1. Verify the default Python version:
   python3 --version

This should output the version number of Python 3.10.

Running Python 3.10 Scripts

With Python 3.10 installed, you can run Python scripts using the python3.10 command or the default python3 command if you’ve set Python 3.10 as the default version.
