import os
class GetPath():# 获取所有目录
    @staticmethod
    def get_dir(path):
        print("打印所有目录：")
        for root, dirs, files in os.walk(path):
            for dir in dirs:
                print(os.path.join(root,dir))

    @staticmethod
    def get_file(path): # 获取文件路径
        print("所有文件路径是：")
        for root, dirs, files in os.walk(path):
            for file in files:
                print(os.path.join(root,file))

if __name__ == '__main__':
    path="/opt"
    GetPath.get_dir(path)
    GetPath.get_file(path)
