Updating Python: Linux
For Linux users, Python can be updated using the package management system, such as APT for Debian-based distributions or YUM for Fedora-based distributions. Here are the steps to follow:
- Check your current Python version: Open a terminal and type in `python3 –version` then hit enter. The terminal will display the Python version you currently have installed.
- Update the package list: Before installing a new Python version, it is a good idea to update the package list. Use `sudo apt-get update` command if you use a Debian-based system, or `sudo yum update` for Fedora-based, then hit enter.
- Install the new Python version: You can install the newest Python release by typing `sudo apt-get install python3.8` (replace 3.8 with your desired version) for Debian-based systems, or `sudo yum install python3.8` for Fedora-based systems in the terminal.
- Verify the update: To ensure the installation was successful, go back to your terminal and type `python3 –version`. You should see the new Python version that you’ve just installed.
Note: Different Linux distributions may have their own package management systems and related commands, so you may need to adjust these instructions accordingly. Remember to update your Python projects, Integrated Development Environment (IDE), and virtual environments to this new version to avoid any discrepancies and conflicts.
