The Script Mode on the other hand allows you to type in instructions into a file, which is then used by the interpreter for execution of the instruction. Thus instead of having to run one line or block of code as in interactive mode you can type up all your code in one text file, or script, and run all the code at once. Such files should have the extension ‘.py’.
