python IDLE 背景以及字体的修改

为了保护眼睛，决定把白色背景换掉：
1 首先，在已经下载好的python文件目录下，找到config-highlight.def文件，我的是在H:\python\python3**\Lib\idlelib**文件夹下。
2.打开文件后，你会看到一些默认的颜色配置，比如经典的颜色配置就是白色背景，一般这个文件中会有两种配置可供选择：
[IDLE Classic]和
[IDLE New]，表现在IDLE界面上就是在python shell下，选择options—configure IDLE—-highlighting选项中，右侧的highlighting theme主题选择，有两种可选方案，就上文件中的那两种。
3.如果直接在源文件上修改颜色有些麻烦，除非你特别熟悉颜色。网上有经典的背景配置：

[Obsidian]definition-foreground = #678CB1error-foreground = #FF0000string-background = #293134keyword-foreground = #93C763normal-foreground = #E0E2E4comment-background = #293134hit-foreground = #E0E2E4builtin-background = #293134stdout-foreground = #678CB1cursor-foreground = #E0E2E4break-background = #293134comment-foreground = #66747Bhilite-background = #2F393Chilite-foreground = #E0E2E4definition-background = #293134stderr-background = #293134hit-background = #000000console-foreground = #E0E2E4normal-background = #293134builtin-foreground = #E0E2E4stdout-background = #293134console-background = #293134stderr-foreground = #FB0000keyword-background = #293134string-foreground = #EC7600break-foreground = #E0E2E4error-background = #293134[tango]definition-foreground = #fce94ferror-foreground = #fa8072string-background = #2e3436keyword-foreground = #8cc4ffnormal-foreground = #ffffffcomment-background = #2e3436hit-foreground = #ffffffbreak-foreground = #000000builtin-background = #2e3436stdout-foreground = #eeeeeccursor-foreground = #fce94fhit-background = #2e3436comment-foreground = #73d216hilite-background = #edd400definition-background = #2e3436stderr-background = #2e3436break-background = #2e3436console-foreground = #87ceebnormal-background = #2e3436builtin-foreground = #ad7fa8stdout-background = #2e3436console-background = #2e3436stderr-foreground = #ff3e40keyword-background = #2e3436string-foreground = #e9b96ehilite-foreground = #2e3436error-background = #2e3436

直接把上面的代码copy到刚才打开的config-highlight.def文件中，然后重启shell就可以。
重启后，shell会默认选择原来的。你就在highlighting theme主题中查看，此时已经多了两种主题，就是你刚才添加的。

主题名字为tango..
大功告成。。

字体的修改

在setting中，如果你设置的字体是中文字体，再怎么修改大小也是没有用的。必须把字体改为英文字体才行。。
