1. REPL环境

1. 下载安装python
2. 环境变量配置，直到cmd内输入python可以打开交互式解释器
3. sublime安装插件SublimeREPL
4. 打开sublime->preferences->Key bindings,输入

	[
	 {
	     "keys": ["f5"],
	     "caption": "SublimeREPL: Python - RUN current file",
	     "command": "run_existing_window_command",
	     "args": {
	         "id": "repl_python_run",
	         "file": "config/Python/Main.sublime-menu"}
     },
     {
	     "keys": ["alt+f5"],
	     "caption": "SublimeREPL: Python - PDB current file",
	     "command": "run_existing_window_command",
	     "args": {
	         "id": "repl_python_pdb",
	         "file": "config/Python/Main.sublime-menu"}
 	},
 	{
	     "keys": ["f8"],
	     "caption": "SublimeREPL: Python",
	     "command": "run_existing_window_command",
	     "args": {
	         "id": "repl_python",
	         "file": "config/Python/Main.sublime-menu"}
 	}, 
]

现在，如果当前是一个py文件，ctrl+B是运行，F5是运行（可输入），alt+F5是调试，f8是打开交互式解释器。

2. py2和py3共存

1. 配好环境变量（python.exe表示py3，python2.exe表示py2）
2. 打开C:\Users\用户名\AppData\Roaming\Sublime Text 3\Packages\User，将以下文件保存为python_littlefall.sublime-build；
3. 进入sublime，选择Tools->Build System->python_littlefall；
4. 完成，按ctrl+b即可运行py文件。默认选项是python3+命令行，其它选项分别是python3+sublime，python2+命令行，python3终端，python2终端，可按ctrl+shift+b切换。
