运行 文件在 IDLE window 直接从命令行

Running file in IDLE window from command line directly

因此，我可以在 (Windows) cmd:

中使用以下命令打开文件以使用 IDLE 进行编辑 
python -m idlelib main.py
# not sure if there's a better way to do that

但是，有没有办法 运行 文件并让它的输出直接打开一个新的 IDLE window（或者切换到当前打开的文件）？

是，使用帮助部分中描述的 -r 选项：

USAGE: 
   idle  [-deins] [-t title] [file]*
   idle  [-dns] [-t title] (-c cmd | -r file) [arg]*
   idle  [-dns] [-t title] - [arg]*

-h         print this help message and exit
-n         run IDLE without a subprocess (DEPRECATED,
           see Help/IDLE Help for details)

The following options will override the IDLE 'settings' configuration:

-e         open an edit window
-i         open a shell window

The following options imply -i and will open a shell:

-c cmd     run the command in a shell, or
-r file    run script from file

-d         enable the debugger
-s         run $IDLESTARTUP or $PYTHONSTARTUP before anything else
-t title   set title of shell window
....

所以，你会这样做：

python -m idlelib -r main.py
