Python is one of the most popular interpreted programming languages, meaning it executes code line by line. Python includes an interactive shell that is used to execute a single Python command to get the output. This is also known as REPL (Read, Evaluate, Print, Loop), because it reads the command, evaluates it, prints the result, then loops back to read the command.

When installing Python on a computer, the Python interpreter is normally installed by default in “/usr/local/bin/python3.8,” but in Unix, if the shell’s search path is set to “/usr/local/bin,” it may be simply started by running the python3.8 command. Now, because directory selection is an installation option where the interpreter is present, other locations are possible as well. You can check with your system administrator about this. (for example, /usr/local/python).
