本文介绍了一个用于注册Python环境变量的Python脚本，该脚本能自动将Python安装路径写入Windows注册表，确保Python及其库能在系统中正确使用。

HKEY_CURRENT_USER\Software\Python\PythonCore\2.7\InstallPath
    default: D:\Python\
    ExecutablePath: D:\Python\python.exe
    WindowedExecutablePath: D:\Python\pythonw.exe

HKEY_CURRENT_USER\Software\Python\PythonCore\2.7\PythonPath
    default: D:\Python\Lib\;D:\Python\DLLs\

# Python extensions that require Python registry settings
