Change Python to Python3 in Linux | Set python to run Python3 in Linux | Using Alias Function

The ‘python’ program command executes Python2. Python3 should be executed using the python3 command, but python3 can be executed by using the command ‘python’. You can learn “How can Python 3 be executed using the python command?”

Currently, I am using Kali Linux to set Python3 to be executed using the python command.

You will be able to:

1. Set ‘python’ program command execute Python3
2. Set cls to clear screen in Linux (Kali Linux, Ubuntu, Fedora, Debian)
3. Set pip3 as default pip installer (‘pip’ program command execute pip3)

Applicable Operating Systems: Kali Linux, Ubuntu, Debian, Fedora, etc.
