Nov 02,  · Python has reached end-of-life. Python , the final release of the series, is available here. Python was released on November 1st, Sep 13,  · Major new features of the series, compared to Among the new major new features and changes in the release series are. PEP , improved Python zip application support; PEP , additional unpacking generalizations; PEP , “%-formatting” for bytes and bytearray objects; PEP , a new operator (@) for matrix multiplication; PEP , r(), a fast new directory . I see you’ve already got Python installed. To get IDLE to use the appropriate version, you need to set IDLE to use that version of Python by changing the shebang line in the IDLE-python file. This is probably located somewhere like /usr/bin/idle-python The contents of .

The turtle module is an extended reimplementation of the same-named module from the Python standard distribution up to version Python It tries to keep the merits of the old turtle module and to be (nearly) % compatible with it.

It is possible to have multiple editor windows simultaneously. They currently have the same top menu as Editor windows but a different default title and context menu. Each menu documented below indicates which window type it is associated with. 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 see below.

On OS X, open the configuration dialog by selecting Preferences in the application menu. Non-default user settings are saved in a. Problems caused by bad user configuration files are solved by editing or deleting one or more of the files in. The rest of this menu lists the names of all open windows; select one to bring it to the foreground deiconifying it if necessary. Open a context menu by right-clicking in a window Control-click on OS X. 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. Backspace deletes to the left; Del deletes to the right. C-Backspace delete word left; C-Del delete word to the right. 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 for functions, classes, and attributes of classes, both built-in and user-defined. Completions are also provided for filenames. If after one of those characters plus zero or more other characters a tab is typed the ACW will open immediately if a possible continuation is found.

If there is only one possible completion for the characters entered, a Tab will supply that completion without opening the ACW. In an empty string, this will contain the files in the current directory. On a blank line, it will contain the built-in and user-defined functions and classes in the current name spaces, plus any modules imported.

If some characters have been entered, the ACW will attempt to be more specific. If a string of characters is typed, the ACW selection will jump to the entry most closely matching those characters.

Entering a tab will cause the longest non-ambiguous match to be entered in the Editor window or Shell. Two tab in a row will supply the current ACW selection, as will return or a double click.

Completions are currently limited to those in the namespaces. Run the module once with your imports to correct this situation. Note that IDLE itself places quite a few modules in sys. A calltip is shown when one types after the name of an acccessible function. A name expression may include dots and subscripts. A calltip remains until it is clicked, the cursor is moved out of the argument area, or is typed.

When the cursor is in the argument part of a definition, the menu or shortcut display a calltip. A calltip consists of the function signature and the first line of the docstring. For builtins without an accessible signature, the calltip consists of all lines up the fifth line or the first blank line. These details may change. The set of accessible functions depends on what modules have been imported into the user process, including those imported by Idle itself, and what definitions have been run, all since the last restart.

For example, restart the Shell and enter itertools. A calltip appears because Idle imports itertools into the user process for its own use. This could change. Enter turtle. Idle does not import turtle. The menu or shortcut do nothing either.

Enter import turtle and then turtle. In an editor, import statements have no effect until one runs the file. One might want to run a file after writing the import statements at the top, or immediately run an existing file before editing.

C-c interrupts executing command. Idle defaults to black on white text, but colors text with special meanings. For the shell, these are shell output, shell error, user output, and user error. For Python code, at the shell prompt or in an editor, these are keywords, builtin class and function names, names following class and def , strings, and comments. For any text window, these are the cursor when present , found text when possible , and selected text.

Text coloring is done in the background, so uncolorized text is occasionally visible. The marking of debugger breakpoint lines in the editor and text in popups and dialogs is not user-configurable. Files referenced by these environment variables are convenient places to store functions that are used frequently from the IDLE shell, or for executing import statements to import common modules.

In addition, Tk also loads a startup file if it is present. Note that the Tk file is loaded unconditionally. This additional file is. As much as possible, the result of executing Python code with IDLE is the same as executing the same code in a console window. However, the different interface and operation occasionally affects visible results.

For instance, sys. IDLE also replaces sys. When this window has the focus, it controls the keyboard and screen. This is normally transparent, but functions that directly access the keyboard and screen will not work. If sys is reset with importlib. Some consoles only work with a single physical line at a time. IDLE uses exec to run each statement. By default, IDLE executes user code in a separate subprocess via a socket, which uses the internal loopback interface. This connection is not externally visible and no data is sent to or received from the Internet.

If firewall software complains anyway, you can ignore it. If the attempt to make the socket connection fails, Idle will notify you.

Such failures are sometimes transient, but if persistent, the problem may be either a firewall blocking the connecton or misconfiguration of a particular system. Until the problem is fixed, one can run Idle with the -n command line switch.

If IDLE is started with the -n command line switch it will run in a single process and will not create the subprocess which runs the RPC Python execution server. This can be useful if Python cannot create the subprocess or the RPC socket interface on your platform. However, in this mode user code is not isolated from IDLE itself. If your code has been modified, you must reload the affected modules and re-import any specific items e.

For these reasons, it is preferable to run IDLE with the default subprocess if at all possible. The font preferences, highlighting, keys, and general preferences can be changed via Configure IDLE on the Option menu. Keys can be user defined; IDLE ships with four built in key sets. IDLE contains an extension facility.

Peferences for extensions can be changed with Configure Extensions. See the beginning of config-extensions. The default extensions are currently:. Other Graphical User Interface Packages.
