IDLE is Python’s Integrated Development and Learning Environment.
IDLE has the following features:
tkinter GUI toolkitcoded in 100% pure Python, using the tkinter GUI toolkit
cross-platform: works mostly the same on Windows, Unix, and macOS
Python shell window (interactive interpreter) with colorizing +of code input, output, and error messages
multi-window text editor with multiple undo, Python colorizing, +smart indent, call tips, auto completion, and other features
search within any window, replace within editor windows, and search +through multiple files (grep)
debugger with persistent breakpoints, stepping, and viewing +of global and local namespaces
configuration, browsers, and other dialogs
Backspace deletes to the left; Del deletes to the right
-C-Backspace delete word left; C-Del delete word to the right
-Arrow keys and Page Up/Page Down to move around
-C-LeftArrow and C-RightArrow moves by words
-Home/End go to begin/end of line
-C-Home/C-End go to begin/end of file
-Some useful Emacs bindings are inherited from Tcl/Tk:

Some useful Emacs bindings are inherited from Tcl/Tk:
-
- C-a beginning of line
-- C-e end of line
-- C-k kill line (but doesn’t put it in clipboard)
-- C-l center window around the insertion point
-- C-b go backward one character without deleting (usually you can -also use the cursor key for this)
-- C-f go forward one character without deleting (usually you can -also use the cursor key for this)
-- C-p go up one line (usually you can also use the cursor key for -this)
-- C-d delete next character

C-d delete next character
C-d sends end-of-file; closes window if typed at a >>> prompt
Alt-/ (Expand word) is also useful to reduce typing
+C-c interrupts executing command

Command history
Alt-p retrieves previous command matching what you have typed. On +macOS use C-p.
Alt-n retrieves next. On macOS use C-n.
