一个简单的划词翻译脚本

调用百度翻译api的划词翻译脚本

• 需求python3，安装库pyperclip和pyautogui
• 去百度翻译开放平台注册appid
• 在下面代码块命名为translate.py并输入appid和secretkey

Windows系统中

• 下载Hotkey Helper
• 配置如下图所示，其中Hotkey选择想要的快捷键，File选择pythonw.exe的绝对位置，Parameter选择translate.py的绝对位置
  
• 通过鼠标选择文本后，按下快捷键可以快速英汉互译，通过弹窗显示结果，其中汉译英需要满足第一个字是汉字
• 该脚本也会自动复制翻译结果到剪切板中，按ctrl+v也可以显示文本

Linux或Mac系统中

• 自定义快捷键 $\text{python \{translate.py 绝对位置\}}$python {translate.py 绝对位置}

$\text translate.py$translate.py
