A new clear_cache() function provides the ability to clear the filecmp comparison cache, which uses os.stat() information to determine if the file has changed since the last compare. This can be used, for example, if the file might have been changed and re-checked in less time than the...
Note that IDLE itself places quite a few modules in sys.modules, so much can be found by default, e.g. the re module. If you don’t like the ACW popping up unbidden, simply make the delay longer or disable the extension. 25.5.2.5. Calltips A calltip is shown when one types ( ...
The editing features described in previous subsections work when entering code interactively. IDLE's Shell window also responds to the following keys. C-c中断执行命令 C-dsends end-of-file; closes window if typed at a>>>prompt Alt-/(Expand word) is also useful to reduce typing ...
If one pastes more that one statement into Shell, the result will be a SyntaxError when multiple statements are compiled as if they were one. The editing features described in previous subsections work when entering code interactively. IDLE's Shell window also responds to the following keys. C...

These include system-specific functions that determine whether a key has been pressed and if so, which. The IDLE code running in the execution process adds frames to the call stack that would not be there otherwise. IDLE wraps sys.getrecursionlimit and sys.setrecursionlimit to reduce the effect...
Both the SMTPServer and SMTPChannel classes now accept a decode_data keyword argument to determine if the DATA portion of the SMTP transaction is decoded using the "utf-8" codec or is instead provided to the SMTPServer.process_message() method as a byte string. The default is True for bac...
up to the maximum number of lines defined in the Configure IDLE dialog (which defaults to 15). If there are no current context lines and the feature is toggled on, a single blank line will display. Clicking on a line in the context pane will move that line to the top of the editor....
