Install idle

Remove trailing space and other whitespace characters after the last non-whitespace character of a line by applying str. Except for Shell windows, remove extra newlines at the end of the file.

Do Check Module. If no error, restart the shell to clean the environment, then execute the module. Output is displayed in the Shell window. Note that output requires use of print or write.

When execution is complete, the Shell retains focus and displays a prompt. At this point, one may interactively explore the result of execution. This is similar to executing a file with python -i file at a command line. Same as Run Module , but run the module with customized settings. Command Line Arguments extend sys.

The module can be run in the Shell without restarting. Check the syntax of the module currently open in the Editor window. If the module has not been saved IDLE will either prompt the user to save or autosave, as selected in the General tab of the Idle Settings dialog. If there is a syntax error, the approximate location is indicated in the Editor window.

Look on the current line. If found, open the file if not already open, and show the line. Use this to view source lines referenced in an exception traceback and lines found by Find in Files.

Also available in the context menu of the Shell window and Output windows. When activated, code entered in the Shell or run from an Editor will run under the debugger. In the Editor, breakpoints can be set with the context menu. This feature is still incomplete and somewhat experimental. Show the stack traceback of the last exception in a tree widget, with access to locals and globals. Open a configuration dialog and change preferences for the following: fonts, indentation, keybindings, text color themes, startup windows and size, additional help sources, and extensions.

On macOS, open the configuration dialog by selecting Preferences in the application menu. For more details, see Setting preferences under Help and preferences. Most configuration options apply to all windows or all future windows. The option items below only apply to the active window. Open a pane at the top of the edit window which shows the block context of the code which has scrolled above the top of the window. See Code Context in the Editing and Navigation section below.

Open a column to the left of the edit window which shows the number of each line of text. The default is off, which may be changed in the preferences see Setting preferences. Toggles the window between normal size and maximum height. The maximum height for a screen is determined by momentarily maximizing a window the first time one is zoomed on the screen. Changing screen settings may invalidate the saved height. This toggle has no effect when a window is maximized.

Lists the names of all open windows; select one to bring it to the foreground deiconifying it if necessary. Display this IDLE document, detailing the menu options, basic editing and navigation, and other tips. Access local Python documentation, if installed, or start a web browser and open docs. See the Help sources subsection below for more on Help menu choices. Open a context menu by right-clicking in a window Control-click on macOS. Context menus have the standard clipboard functions also on the Edit menu.

Editor windows also have breakpoint functions. Lines with a breakpoint set are specially marked. Breakpoints only have an effect when running under the debugger. The Shell window also has an output squeezing facility explained in the Python Shell window subsection below. Thereafter, use the File menu. There can be only one open editor window for a given file. The title bar contains the name of the file, the full path, and the version of Python and IDLE running the window.

Line numbers start with 1; column numbers with 0. IDLE assumes that files with a known. Run Python code with the Run menu. Backspace deletes to the left; Del deletes to the right. C - Backspace delete word left; C - Del delete word to the right. C - a beginning of line.

C - e end of line. 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. Standard keybindings like C - c to copy and C - v to paste may work. After a block-opening statement, the next line is indented by 4 spaces in the Python Shell window by one tab. After certain keywords break, return etc. In leading indentation, Backspace deletes up to 4 spaces if they are there.

Tab inserts spaces in the Python Shell window one tab , number depends on Indent width. Completions are supplied, when requested and available, for module names, attributes of classes or functions, or filenames. Each request method displays a completion box with existing names. See tab completions below for an exception. For any box, change the name being completed and the item highlighted in the box by typing and deleting characters; by hitting Up , Down , PageUp , PageDown , Home , and End keys; and by a single click within the box.

Close the box with Escape , Enter , and double Tab keys or clicks outside the box. A double click within the box selects and closes. One way to open a box is to type a key character and wait for a predefined interval.

This defaults to 2 seconds; customize it in the settings dialog. To prevent auto popups, set the delay to a large number of milliseconds, such as For filenames in the root directory, type os. On Windows, one can specify a drive first. Move into subdirectories by typing a directory name and a separator. Instead of waiting, or after a box is closed, open a completion box immediately with Show Completions on the Edit menu.

The default hot key is C - space. If one types a prefix for the desired name before opening the box, the first match or near miss is made visible. The result is the same as if one enters a prefix after the box is displayed.
