Are you on a unix system? You could shell out to `file` – Daenyth Mar 25 '12 at 18:30 — Daenyth, Mar 25 '12 at 18:30

You can use the Python built-in mimetypes module for this. I believe this module relies solely on the file name and not its contents.

You could use the python-magic library:

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

It's not a builtin module. Did you read the installation instructions at the link I provided? You can ``pip install python-magic`` or ``easy_install python-magic`` – jterrace Mar 25 '12 at 18:39
@Eng_Engineer the link has installation instructions for windows – jterrace Mar 25 '12 at 18:41
:Sorry but in this link i don't know what can i download exactly to install magic.dll(http://gnuwin32.sourceforge.net/) – Computer_Engineer Mar 25 '12 at 18:43
@Eng_Engineer try [this link](http://downloads.sourceforge.net/project/getgnuwin32/getgnuwin32/0.6.30/GetGnuWin32-0.6.3.exe?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fgetgnuwin32%2Ffiles%2Fgetgnuwin32%2F0.6.30%2F&ts=1332701160&use_mirror=voxel) – jterrace Mar 25 '12 at 18:46
:i installed Automated gnuwin32 download tool from this link,what should i do next step? – Computer_Engineer Mar 25 '12 at 18:50
magic1.dll, regex2.dll and zlib1.dll all need to be in system32 directory – jterrace Mar 25 '12 at 19:21
these two files aren't exist in the GetGnuWin32,BTW i used mime=mimetypes.guess_type(name)[0] to get the mime type and it's worked correctly,Thanks for your help. – Computer_Engineer Mar 25 '12 at 19:24
those files are definitely part of gnuwin32. just note that mimetypes relies on the file extension, not the file contents itself – jterrace Mar 25 '12 at 19:46
