1. 打开Sublime text 3 安装package control

Sublime Text 3 安装Package Control

2. 安装 SublimeREPL

Ctrl+shift+p 键入 install packages
稍等片刻后 键入 SublimeREPL 安装即可
通过选项Tools->SublimeREPL->Python就可以看到效果了

3. 键位绑定

当然每次通过Tools->SublimeREPL->Python这样的方式比较繁琐
将这样的操作和一个按键如F1绑定后，就会方便很多啦

打开Preferences->Key Bindings-User，复制一下代码：

{"keys":["f1"],
"caption": "SublimeREPL: Python",
"command": "run_existing_window_command", "args":
{"id": "repl_python",
"file": "config/Python/Main.sublime-menu"}}

Ctrl+s下就好了~

相较于纯白如雪的原版idle,Sublime实在是色彩缤纷:-)
ps 如果还想编译下热乎乎的py代码，可以复制以下代码：

{"keys":["f2"],
"caption": "SublimeREPL: Python - RUN current file",
"command": "run_existing_window_command", "args":
{"id": "repl_python_run",
"file": "config/Python/Main.sublime-menu"}}

如果要同时实现F1 和 F2（复制的时候记得中间加个逗号……）：

{"keys":["f1"],
"caption": "SublimeREPL: Python",
"command": "run_existing_window_command", "args":
{"id": "repl_python",
"file": "config/Python/Main.sublime-menu"}}

,

{"keys":["f2"],
"caption": "SublimeREPL: Python - RUN current file",
"command": "run_existing_window_command", "args":
{"id": "repl_python_run",
"file": "config/Python/Main.sublime-menu"}}
