The 3.0 version of Python is often called Python 3000, or Py3k for short. This is a major upgrade compared to earlier versions of Python. In order not to bring too much burden, Python 3.0 was not designed with backward compatibility in mind.

On Linux/Unix systems, the default python version is generally 2.x. We can install python3.x in the /usr/local/python3 directory. After the installation is complete, we can add the path /usr/local/python3/bin to the environment variable of your Linux/Unix operating system, so that you can enter the following command through the shell terminal to start Python3.
