Basic editing and navigation
|
|
----------------------------
|
|
|
|
* :kbd:`Backspace` deletes to the left; :kbd:`Del` deletes to the right
|
|
|
|
* Arrow keys and :kbd:`Page Up`/:kbd:`Page Down` to move around
|
|
|
|
* :kbd:`Home`/:kbd:`End` go to begin/end of line
|
|
|
|
* :kbd:`C-Home`/:kbd:`C-End` go to begin/end of file
|
|
|
|
* Some :program:`Emacs` bindings may also work, including :kbd:`C-B`,
|
|
:kbd:`C-P`, :kbd:`C-A`, :kbd:`C-E`, :kbd:`C-D`, :kbd:`C-L`
|
|
|
|
|
|
Automatic indentation
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
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.)
|
|
the next line is dedented. In leading indentation, :kbd:`Backspace` deletes up
|
|
to 4 spaces if they are there. :kbd:`Tab` inserts 1-4 spaces (in the Python
|
|
Shell window one tab). See also the indent/dedent region commands in the edit
|
|
menu.
|
|
|
|
|
|
Python Shell window
|
|
^^^^^^^^^^^^^^^^^^^
|
|
|
|
* :kbd:`C-C` interrupts executing command
|
|
|
|
* :kbd:`C-D` sends end-of-file; closes window if typed at a ``>>>`` prompt
|
|
|
|
* :kbd:`Alt-p` retrieves previous command matching what you have typed
|
|
|
|
* :kbd:`Alt-n` retrieves next
|
|
|
|
* :kbd:`Return` while on any previous command retrieves that command
|
|
|
|
* :kbd:`Alt-/` (Expand word) is also useful here

Syntax colors
|
|
-------------
|
|
|
|
The coloring is applied in a background "thread," so you may occasionally see
|
|
uncolorized text. To change the color scheme, edit the ``[Colors]`` section in
|
|
:file:`config.txt`.

Command line usage
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
::
|
|
|
|
idle.py [-c command] [-d] [-e] [-s] [-t title] [arg] ...
|
|
|
|
-c command run this command
|
|
-d enable debugger
|
|
-e edit mode; arguments are files to be edited
|
|
-s run $IDLESTARTUP or $PYTHONSTARTUP first
|
|
-t title set title of shell window
|
|
|
|
If there are arguments:
|
|
|
|
#. If :option:`-e` is used, arguments are files opened for editing and
|
|
``sys.argv`` reflects the arguments passed to IDLE itself.
|
|
|
|
#. Otherwise, if :option:`-c` is used, all arguments are placed in
|
|
``sys.argv[1:...]``, with ``sys.argv[0]`` set to ``'-c'``.
|
|
|
|
#. Otherwise, if neither :option:`-e` nor :option:`-c` is used, the first
|
|
argument is a script which is executed with the remaining arguments in
|
|
``sys.argv[1:...]`` and ``sys.argv[0]`` set to the script name. If the script
|
|
name is '-', no script is executed but an interactive Python session is started;
|
|
the arguments are still available in ``sys.argv``.
