Clicking File Icons
On Windows, the Registry makes opening files with icon clicks easy. Python automatically registers itself to be the program that opens Python program files when they are clicked. Because of that, it is possible to launch the Python programs you write by simply clicking (or double-clicking) on their file icons with your mouse cursor.
On non-Windows systems, you will probably be able to perform a similar trick, but the icons, file explorer, navigation schemes, and more may differ slightly. On some Unix systems, for instance, you may need to register the .py extension with your file explorer GUI, make your script executable using the #! trick discussed in the previous section, or associate the file MIME type with an application or command by editing files, installing programs, or using other tools. See your file explorer’s documentation for more details if clicks do not work correctly right off the bat.
