How to find the mime type of a file in python?

I want to detect the type of a file, but I don't want to look at the extension because it may be incorrect. The mimetypes module is filename based.

Is there a standard way to peek inside the file?

尝试安装python-magic模块。

 >>> mime = magic.Magic(mime=True)
 >>> mime.from_file("testdata/abc.pdf")
'application/pdf'
