★3.4+ On UNIX-like systems, such as Linux, macOS, and UNIX itself, function input (Tip 9, Let input() Speak for Itself) uses the POSIX readline interface. The interface offers extended capabilities:
- Editing: moving the cursor backward and forward; deleting, inserting, and replacing characters; copying and pasting strings
- Configuration: modifying key bindings, adding pre-recorded macros, and even defining variables — all via the ~/.inputrc file
- History: scrolling for the previously entered strings with the Up and Down keys; searching through the history (with Ctrl+r)
A detailed explanation of the readline functionality is outside the scope of the book. You can read more about it in the manual (man readline).
Bear in mind that the readline used by input and the readline used by the Python console command line is the same readline. Anything you typed on the console will show up in the input history and the other way around.
