1. python3 new build system

{

    "cmd": ["C:/path/python.exe","-u","$file"],

    "file_regex":"^[ ]*File \"(...*?)\", line ([0-9]*)",

    "selector":"source.python",

}

2. package control install sublimerepl
需要连接vpn

3. 设置快捷键
preferences->Key Binding-User，写入以下内容

[
    { "keys": ["f5"], "caption": "SublimeREPL:Python", 
                      "command": "run_existing_window_command", "args":
                      {
                           "id": "repl_python_run",
                           "file": "config/Python/Main.sublime-menu"
                      } 
    },
]

4. 快捷键
发现sublime真是好用啊。
