Python has gone through tremendous improvement in the past few years.
There was a time when Python 2.7 was alongside the Python 3 versions. Yet, versions in major release three have outgrown the 2.7. As a result, Python officially ended support for 2.7 in 2020.
Meanwhile, the subsequent versions of Python 3 have excellent improvements. The introduction of f-strings in version 3.6, data classes in 3.10, and performance boost in 3.11 are noticeable improvements.

If you want to install the latest stable release of Python 3.12 on Ubuntu, you can follow the same steps but download the latest stable release from the Python downloads page instead of the development version.
Test your Python 3.12 Installation
After installing Python 3.12 on Ubuntu, you can access it in a few different ways:

myscript.py, you can use the following command:
2. You can also use the
python3.12 command to enter the Python interactive interpreter, which allows you to enter and execute Python commands directly. To start the interactive interpreter, run the
python3.12 command with no arguments:
3. If you have multiple versions of Python installed on your system and want to ensure that Python 3.12 is the default version, you can update the
python3 symlinks to point to Python 3.12. For example, you can run the following commands to update the symlinks:
sudo ln -sf /usr/local/bin/python3.12 /usr/local/bin/python sudo ln -sf /usr/local/bin/python3.12 /usr/local/bin/python3
Please note that these instructions are specific to Ubuntu, and the exact steps may vary depending on your particular distribution and installation method.
Python 3.12 is still in development, so it is unsuitable for production use. It is only intended for testing and development purposes and may contain bugs and unfinished features.
That being said, Python 3.12 is expected to include several new features and improvements over previous versions of Python. You can find more information about the proposed features for Python 3.12 in the Python Developer's Guide.
