Import statements to import common modules.In addition, Tk also loads a startup file if it is present. Note that theTk file is loaded unconditionally. This additional file is .Idle.py and islooked for in the user’s home directory. Statements in this file will beexecuted in the Tk namespace, so this file is not useful for importingfunctions to be used from IDLE’s Python shell.25.5.3.1. Command line usage¶idle.py [-c command] [-d] [-e] [-h] [-i] [-r file] [-s] [-t title] [-] [arg] ...-c command run command in the shell window-d enable debugger and open shell window-e open editor window-h print help message with legal combinatios and exit-i open shell window-r file run file in shell window-s run $IDLESTARTUP or $PYTHONSTARTUP first, in shell window-t title set title of shell window- run stdin in shell (- must be last option before args)If there are arguments:If -, -c, or r is used, all arguments are placed insys.argv[1:...] and sys.argv[0] is set to '', '-c',or '-r'. No editor window is opened, even if that is the defaultset in the Options dialog.Otherwise, arguments are files opened for editing andsys.argv reflects the arguments passed to IDLE itself.25.5.3.2. IDLE-console differences¶As much as possible, the result of executing Python code with IDLE is thesame as executing the same code in a console window. However, the differentinterface and operation occasionally affects results.For instance, IDLE normally executes user code in a separate process fromthe IDLE GUI itself. The IDLE versions of sys.stdin, .stdout, and .stderr in theexecution process get input from and send output to the GUI process,which keeps control of the keyboard and screen. This is normally transparent,but code that access these object will see different attribute values.Also, functions that directly access the keyboard and screen will not work.With IDLE’s Shell, one enters, edits, and recalls complete statements.Some consoles only work with a single physical line at a time.25.5.3.3. Running without a subprocess¶By default, IDLE executes user code in a separate subprocess via a socket,which uses the internal loopback interface. This connection is notexternally visible and no data is sent to or received from the Internet.If firewall software complains anyway, you can

What is Python IDLE and How to Use the IDLE Shell - YouTube

Without an accessible signature, the calltipconsists of all lines up the fifth line or the first blank line. Thesedetails may change.The set of accessible functions depends on what modules have been importedinto 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.count(. A calltipappears because Idle imports itertools into the user process for its own use.(This could change.) Enter turtle.write( and nothing appears. Idle doesnot import turtle. The menu or shortcut do nothing either. Enterimport turtle and then turtle.write( will work.In an editor, import statements have no effect until one runs the file. Onemight want to run a file after writing the import statements at the top,or immediately run an existing file before editing.25.5.2.4. Python Shell window¶C-c interrupts executing commandC-d sends end-of-file; closes window if typed at a >>> promptAlt-/ (Expand word) is also useful to reduce typingCommand historyAlt-p retrieves previous command matching what you have typed. OnOS X use C-p.Alt-n retrieves next. On OS X use C-n.Return while on any previous command retrieves that command25.5.2.5. Text colors¶Idle defaults to black on white text, but colors text with special meanings.For the shell, these are shell output, shell error, user output, anduser error. For Python code, at the shell prompt or in an editor, these arekeywords, builtin class and function names, names following class anddef, strings, and comments. For any text window, these are the cursor (whenpresent), found text (when possible), and selected text.Text coloring is done in the background, so uncolorized text is occasionallyvisible. To change the color scheme, use the Configure IDLE dialogHighlighting tab. The marking of debugger breakpoint lines in the editor andtext in popups and dialogs is not user-configurable.25.5.3. Startup and code execution¶Upon startup with the -s option, IDLE will execute the file referenced bythe environment variables IDLESTARTUP or PYTHONSTARTUP.IDLE first checks for IDLESTARTUP; if IDLESTARTUP is present the filereferenced is run. If IDLESTARTUP is not present, IDLE checks forPYTHONSTARTUP. Files referenced by these environment variables areconvenient places to store functions that are used frequently from the IDLEshell, or for executing

Can set in the “idle” handler how often the remote training should occur.The first time you run the script, it may take a long time if there are lots of messages in the training mailboxes. It will wait for three minutes for Mail to fetch the messages before giving up. You can speed this up by manually training those messages.The script may also take a long time to run if the training mailboxes contain lots of messages that Mail has deleted but not yet purged. You can speed this by up deleting and recreating the training mailboxes to get rid of those messages.Note: On macOS 10.8 or later, the script must be saved in the folder /Users//Library/Application Scripts/com.apple.mail. This is because Mail is sandboxed and only has access to run scripts in that folder. To access the Library folder, click on the Go menu in the Finder while holding down the Option key.Installation Instructions · Download in Compiled Format · Download in Text FormatScriptproperty pMarkSpamMessagesRead : falseproperty pColorSpamMessages : trueproperty pFlagSpamMessages : falseproperty pMarkGoodMessagesUnread : falseproperty pMoveBySettingMailbox : trueproperty pSpamMailboxName : "Spam"property pEnableDebugLogging : falseglobal useJunkMailboxon accountNamesForDrone() return {"Account 1"}end accountNamesForDroneon spamMailboxNamesByAccount() return {}end spamMailboxNamesByAccounton hostNameForDrone() return "" set {_host} to my lookupDefaults({"AppleMailEnabledHostName"}, {""}) return _hostend hostNameForDroneon debugLog(_message) if pEnableDebugLogging then my logToConsole(_message)end debugLogon logToConsole(_message) set _logMessage to "SpamSieve [Apple Mail Remote Training MJTLog] " & _message do shell script "/usr/bin/logger -s " & _logMessage's quoted formend logToConsoleon run my doRemoteTraining()end runon idle my doRemoteTraining() return 60 * 5 end
