We can access Python's interactive console from any computer that has Python already installed. Run the following command to start Python's interactive console:
$ python
This will start the default Python interactive console.
In Linux, if we write Python in the Terminal, the python2.7 console starts. If you want to start the python3 console, then enter python3 in the Terminal and press Enter.
In Windows, when you enter Python in Command Prompt, it will start the console of the downloaded Python version.
