The package simply points python command (and binary path) to Python 3.ĭoes python-is-python3 really just create a single symlink? You may wonder why introducing a separate package for such a bare bone purpose. That’s where python-is-python3 package comes into play. But a lot of them still expect python to be Python 2.x, renders the program unusable on Ubuntu 20.04 and later. Newer versions of popular software acknowledge this change and update their code accordingly, so that the programs does not accidentally run Python 3 code in Python 2.x, which leads to errors.

Because of that, python command now points to Python 3. Only Python 3 is shipped with the OS out of the box. On Ubuntu 20.04 onwards, the developers removed and modified the legacy source code so that Python 2 can be removed. Python 2 can be called by running python in a terminal, while python3 is the alias for Python 3. On Ubuntu version 18.10 and older, both Python 2 and Python 3 was shipped with the OS.
