** TIPS **
|
|
==========
|
|
|
|
Additional Help Sources:
|
|
|
|
Windows users can Google on zopeshelf.chm to access Zope help files in
|
|
the Windows help format. The Additional Help Sources feature of the
|
|
configuration GUI supports .chm, along with any other filetypes
|
|
supported by your browser. Supply a Menu Item title, and enter the
|
|
location in the Help File Path slot of the New Help Source dialog. Use
|
|
http:// and/or www. to identify external URLs, or download the file and
|
|
browse for its path on your machine using the Browse button.
|
|
|
|
All users can access the extensive sources of help, including
|
|
tutorials, available at www.python.org/doc. Selected URLs can be added
|
|
or removed from the Help menu at any time using Configure IDLE.
|
|
|
|
Basic editing and navigation:
|
|
|
|
Backspace deletes char to the left; DEL deletes char to the right.
|
|
Control-backspace deletes word left, Control-DEL deletes word right.
|
|
Arrow keys and Page Up/Down move around.
|
|
Control-left/right Arrow moves by words in a strange but useful way.
|
|
Home/End go to begin/end of line.
|
|
Control-Home/End go to begin/end of file.
|
|
Some useful Emacs bindings (Control-a, Control-e, Control-k, etc.)
|
|
are inherited from Tcl/Tk.
|
|
Standard Windows bindings may work on that platform.
|
|
Keybindings are selected in the Settings Dialog, look there.
|
|
|
|
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, 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. (N.B. Currently tabs are restricted to four spaces due
|
|
to Tcl/Tk issues.)
|
|
|
|
See also the indent/dedent region commands in the edit menu.
|
|
|
|
Python Shell window:
|
|
|
|
Control-c interrupts executing command.
|
|
Control-d sends end-of-file; closes window if typed at >>> prompt
|
|
(this is Control-z on Windows).
|
|
|
|
Command history:
|
|
|
|
Alt-p retrieves previous command matching what you have typed.
|
|
Alt-n retrieves next.
|
|
(These are Control-p, Control-n on the Mac)
|
|
Return while cursor is on a previous command retrieves that command.
|
|
Expand word is also useful to reduce typing.
|
|
|
|
Syntax colors:
|
|
|
|
The coloring is applied in a background "thread", so you may
|
|
occasionally see uncolorized text. To change the color
|
|
scheme, use the Configure IDLE / Highlighting dialog.
|
|
|
|
Python default syntax colors:
|
|
|
|
Keywords orange
|
|
Builtins royal purple
|
|
Strings green
|
|
Comments red
|
|
Definitions blue
|
|
|
|
Shell default colors:
|
|
|
|
Console output brown
|
|
stdout blue
|
|
stderr red
|
|
stdin black
|
|
|
|
Other preferences:
|
|
|
|
The font preferences, keybinding, and startup preferences can
|
|
be changed using the Settings dialog.
|
|
|
|
Command line usage:
|
|
|
|
Enter idle -h at the command prompt to get a usage message.
|
|
|
|
Running without a subprocess:
|
|
|
|
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. Also, the
|
|
environment is not restarted when Run/Run Module (F5) is selected. If
|
|
your code has been modified, you must reload() the affected modules and
|
|
re-import any specific items (e.g. from foo import baz) if the changes
|
|
are to take effect. For these reasons, it is preferable to run IDLE
|
|
with the default subprocess if at all possible.
