read() UnsupportedOperation: read如果需要该模式同时支持读写,需要使用 wb+ 模式打开文件:path = 'data_1.txt' if not os.path.exists(path): print(f'{path} 不存在!') else: os.remove(path) print(f'在打开前已经删除了 {path} 文件!') with open(path, 'wb+') as f: f.write(b'hello ...
u= f.read().decode('DeyunCode') 三、文件和目录操作 在图形界面的操作系统下,这个很简单,就是右键/拖拽 等等。 但是在Python的代码内该怎么做呢? 基本操作 用Python内置的os模块直接调用操作系统提供的接口函数: import os os.name 这里是通过OS告诉我们 我的操作系统的名字。 如果是posix,说明系统是#nix族...
