Sublime Text 3配置Python交互环境
今天学Python时遇到如下代码：
#!/usr/bin/python3
# 该实例演示了数字猜谜游戏
number = 7
guess = -1
print("数字猜谜游戏!")
while guess != number:
guess = int(input("请输入你猜的数字："))
if guess == number:
print("恭喜，你猜对了！")
elif guess < number:
print("猜的数字小了...")
elif guess > number:
print("猜的数字大了...")⌘+b执行该段代码后我发现输入数字后，控制台无法进行下一步，无法建立互动，于是Google如何在ST3中建立Python交互环境。
在用ST3学习Python前，我就安装了以下三个据说是学Python必装的Package：
- SublimeCodeIntel
- SublimeLinter
- SublimeREPL
其中SublimeREPL就可以搭建起Python交互环境。
修改SublimeREPL
选择Tools-SublimeREPL-Python-Python-RUN current file，就可以建立起上述代码的交互环境。当我点击了Python-RUN current fileST3又报错，一看还是编码问题，看来还得像上一篇文章一样调整一下SublimeREPL的Python编码。在/Users/你的用户名/Library/Application Support/Sublime Text 3/Packages/SublimeREPL/config/Python或者Preferences-Browse Packages...-SublimeREPL-config-Python路径中找到Main.sublime-menu这个文件打开，定位到caption": "Python - RUN current file"那块，原始代码为：
{"command": "repl_open",
"caption": "Python - RUN current file",
"id": "repl_python_run",
"mnemonic": "R",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python", "-u", "$file_basename"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
},
我改成下面这样：
{"command": "repl_open",
"caption": "Python - RUN current file",
"id": "repl_python_run",
"mnemonic": "R",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python3", "-u", "-i", "$file_basename"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
},这样就解决了RUN current file时的编码问题。但这样还有一个问题，每次需要交互，必须要点击菜单栏Tools然后一层层点进去才能跑代码，还需要设置一个快捷键。
设置快捷键
在Preferences-Key Bindings进行快捷键设置。在显示的文件名为Default (OSX).sublime-keymap - User文档的两个方括号间粘贴如下代码：
{ "keys": ["ctrl+r"],
"command": "repl_open",
"caption": "Python - RUN current file",
"mnemonic": "R",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python3", "-u", "-i", "$file_basename"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
}我设置了ctrl+r为RUN current file的快捷键。
到这里，Python在ST3的交互问题就全部搞定了，并且有了一个快捷键可以快速方便的执行交互类型的代码了。
