使用Sublime Text 3能以輕量級的環境寫python腳本，運行python代碼。為了更加方便地調用python腳本，通過在Sublime Text 3中綁定快捷鍵的方式，實現一鍵調用python交互運行環境，操作方式如下：

1、打開 Sublime text 3 安裝 package control

在Tools目錄下點擊安裝Package Control（最后一個）

2、安裝 SublimeREPL

在Sublime text 3 中，通過快捷鍵 Ctrl+shift+p，鍵入install packages，在彈出的輸入框里面，輸入SublimeREPL。稍等安裝后，即可看到Tools->SublimeREPL->Python菜單

3、綁定快捷鍵 F5（也可以改為其它快捷鍵）

打開菜單Preferences->Key Bindings-User，然后輸入

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

這樣在Sublime Text 3里面輸入python腳本后，保存為py文件，然后只要按一下 F5 ，就能夠一鍵執行python腳本了

由于本人安裝的python有python 2.7和python 3.6兩個版本，默認是python 2.7，所以剛才按F5快捷鍵后就默認跳到python 2.7的默認環境，如果要定義兩個不同的快捷鍵，自由切換python 2.7和python 3.6，那可以這樣做

打開目錄?C:\Users\chinamobile\AppData\Roaming\Sublime Text 3\Packages\SublimeREPL\config\Python

把里面關于cmd python的改為cmd python36。（注：為區分python 2.7，本機的python 3.6命令為python36），修改后如下：

[{"id": "tools","children":[{"caption": "SublimeREPL","mnemonic": "R","id": "SublimeREPL","children":[{"caption": "Python","id": "Python","children":[{"command": "repl_open","caption": "Python","id": "repl_python","mnemonic": "P","args": {"type": "subprocess","encoding": "utf8","cmd": ["python36", "-i", "-u"],"cwd": "$file_path","syntax": "Packages/Python/Python.tmLanguage","external_id": "python","extend_env": {"PYTHONIOENCODING": "utf-8"}}},{"command": "python_virtualenv_repl","id": "python_virtualenv_repl","caption": "Python - virtualenv"},{"command": "repl_open","caption": "Python - PDB current file","id": "repl_python_pdb","mnemonic": "D","args": {"type": "subprocess","encoding": "utf8","cmd": ["python36", "-i", "-u", "-m", "pdb", "$file_basename"],"cwd": "$file_path","syntax": "Packages/Python/Python.tmLanguage","external_id": "python","extend_env": {"PYTHONIOENCODING": "utf-8"}}},{"command": "repl_open","caption": "Python - RUN current file","id": "repl_python_run","mnemonic": "R","args": {"type": "subprocess","encoding": "utf8","cmd": ["python36", "-u", "$file_basename"],"cwd": "$file_path","syntax": "Packages/Python/Python.tmLanguage","external_id": "python","extend_env": {"PYTHONIOENCODING": "utf-8"}}},{"command": "repl_open","caption": "Python - IPython","id": "repl_python_ipython","mnemonic": "I","args": {"type": "subprocess","encoding": "utf8","autocomplete_server": true,"cmd": {"osx": ["python36", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"],"linux": ["python36", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"],"windows": ["python36", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"]},"cwd": "$file_path","syntax": "Packages/Python/Python.tmLanguage","external_id": "python","extend_env": {"PYTHONIOENCODING": "utf-8","SUBLIMEREPL_EDITOR": "$editor"}}}]}]}]}
]

然后在菜單Preferences->Key Bindings-User中，再增加新的快捷鍵，如F6，修改后如下：

[{ "keys": ["f5"], "caption": "SublimeREPL:Python", "command": "run_existing_window_command", "args":{"id": "repl_python_run","file": "config/Python/Main.sublime-menu"} },{ "keys": ["f6"], "caption": "SublimeREPL:Python", "command": "run_existing_window_command", "args":{"id": "repl_python_run","file": "config/Python/Main-python36.sublime-menu"} },
]

這樣就完成了，F5就一鍵切換到python 2.7環境，F6就一鍵切換到python 3.6環境，非常方便
