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. Show Completions after a quote completes filenames in the current directory instead of a root directory.
Hitting Tab after a prefix usually has the same effect as Show Completions. With no prefix, it indents. However, if there is only one match to the prefix, that match is immediately added to the editor text without opening a box. When editing code in an editor as oppose to Shell , increase the available module-level names by running your code and not restarting the Shell thereafter. This is especially useful after adding imports at the top of a file. This also increases possible attribute completions.
A calltip is shown automatically when one types after the name of an accessible function. A function 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. Some builtin functions lack an accessible signature. Details are subject to change. In Shell, the accessible functions depends on what modules have been imported into the user process, including those imported by Idle itself, and which 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 itself import turtle. The menu entry and shortcut also do nothing.
Enter import turtle. Thereafter, turtle. In an editor, import statements have no effect until one runs the file. One might want to run a file after writing import statements, after adding function definitions, or after opening an existing file. Within an editor window containing Python code, code context can be toggled in order to show or hide a pane at the top of the window.
When shown, this pane freezes the opening lines for block code, such as those beginning with class , def , or if keywords, that would have otherwise scrolled out of view. The size of the pane will be expanded and contracted as needed to show the all current levels of context, up to the maximum number of lines defined in the Configure IDLE dialog which defaults to If there are no current context lines and the feature is toggled on, a single blank line will display.
IPython 3. As of IPython 4. IPython itself is focused on interactive Python, part of which is providing a Python kernel for Jupyter. IPython tends to be released on the last Friday of each month, this section updated rarely. Please have a look at the release history on PyPI. Release files for currently supported releases are signed by the following:. Release files for older releases which have now reached end-of-life may have been signed by one of the following:.
You can import a person's public keys from a public keyserver network server you trust by running a command like:. On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file. To verify the authenticity of the download, grab both files and then run this command:. Note that you must use the name of the signature file, and you should use the one that's appropriate to the download you're verifying.
