推荐答案

<代码> io 库可以创建类似于对象的内存文件，这些对象的行为类似于使用典型的 f = open(filename，mode)打开的文件句柄.如果您将以普通文本模式打开，则 StringIO 应该可以解决问题，或者如果您已经以二进制模式打开文件，请

The io library can create in-memory file like objects that act like file handles opened with the typical f = open(filename, mode). If you would have opened in normal text mode, a StringIO should do the trick, or if you would have opened the file in binary mode, BytesIO is the way to go.
