如何从文件类型获取文件扩展名? [英] How can i get a file extension from a filetype?

问题描述

我有以下文件名列表

files = [
    '/dl/files/4j55eeer_wq3wxxpiqm.jpg',
    '/home/Desktop/hjsd03wnsbdr9rk3k',
    'kd0dje7cmidj0xks03nd8nd8a3',
    ...
]

问题是大多数文件的文件名都没有扩展名，什么是获取这些文件扩展名的最佳方法是什么?

The problem is most of the files do not have an extension in the filenames, what would be the best way to get file extension of these files ?

我什至不知道这是否可行，因为python会将所有文件视为没有任何filetype关联的buffer或string对象.

I don't know if this is even possible because python would treat all files as buffer or string objects that do not have any filetype associated with them.

这完全可以做到吗?

推荐答案

一旦使用magic获取MIME类型，就可以使用

Once you use magic to get the MIME type, you can use mimetypes.guess_extension() to get the extension for it.
