os模块

    def copy(self,src_path,target_path):
        os.mkdir(target_path)
        if os.path.isdir(src_path):
            for file in os.listdir(src_path):
                path=os.path.join(src_path,file)
                if os.path.isdir(path):
                    path1=os.path.join(target_path,file)
                    os.mkdir(path1)
                    self.copy(path,path1)
                else:
                    with open(path,"rb") as f1:
                        container=f1.read()
                        path2=os.path.join(target_path,file)
                        with open(path2,"wb") as f2:
                            f2.write(container)

pathlib模块

    def copy(originPath,newPath):
        originPath=Path(originPath).resolve()
        newPath=Path(newPath).resolve()
        if originPath.is_file():
            (newPath/originPath.name).write_text(originPath.read_text(encoding="utf-8"),encoding="utf-8")
        else:
            if not newPath.exists():
                Path.mkdir(newPath)
            for dof in originPath.iterdir():
                FILE_HELPER.copy(dof,newPath/dof.name if dof.is_dir() else newPath)

总的来说pathlib模块还是方便很多。
