使用python从操作系统获取软件包扩展

import pkg_resources

def get_package_extensions():
    installed_packages = pkg_resources.working_set
    extensions = []

    for package in installed_packages:
        # 获取软件包的元数据
        metadata = package.get_metadata(package.PKG_INFO)
        
        # 检查是否有软件包扩展字段
        if 'Extension' in metadata:
            extension_info = metadata['Extension']
            extensions.append(extension_info)
    
    return extensions

extensions = get_package_extensions()
print(extensions)
