Alan, i know that every site has a search function, but they're not so
simple to be used if you're looking for a very common word ("in") and
don't know other keys to find it.

Sander, sorry for the top-posting, it's the default in GMail. This is
one of my first times in a mailing list, so it's possible i'm doing
something wrong. Sorry again for it.

Found an example some seconds ago in another mailing lists. I'm not
able to find the python tutorial that describes this statement. Can

Probably ctypes is not supported in GAE, that would be a pretty big
security hole.

Re: [Tutor] Determine Filetype
Ops, i have another question, it seems very simple.
I want to check the extension of an uploaded file. So i've created a
list with allowed extensions:
enabled_ext = ['gif', 'jpeg', 'png', 'bmp', 'tiff']
How can i create a simple if that check if the file ext (file_ext) is
in the list?
I've searched in the python tutorial, but have not been able to find
any example that uses an if statement combined with a list.

Re: [Tutor] Determine Filetype
Hi All,
the solution was in the link i've posted before. If i use:
type = imghdr.what('img.test', image.data)
The imghdr modules ignore the filename (first argument) and takes the
second as a data stream assumed to contain the filetype.
The solution only works for images, but that's what i need. I think
that right now is not possible to generally determine the mimetype for
all types of files on GAE, because some libraries are missing. Anyway,
i'll send a mail to the gae mailing list, and if find a solution i'll
post it here.
Thankyou all guys.

Re: [Tutor] Determine Filetype
Ok, a good news for me:
i've modified my script, adding a:
import magic
line at the top of it. But I got this error:
No module named magic
Ok, so magic is not installed on GAE. I've then uploaded it and it
loaded succesfully. New error:
No module named _ctypes
And, reading the full debug i got this:
File "/base/python_dist/lib/python2.5/ctypes/__init__.py", line 10, in
from _ctypes import Union, Structure, Array
So, the __init__.py file of the GAE evinronment's ctypes library is
broken, as it's importing from a package that doesn't exist. Right?
Maybe i'm doing something wrong.

Hi Emile,
that functions requires a filename/path. Just like this one (for images)
http://docs.python.org/library/imghdr.html
Ok, i don't have a filename. I get the file from a BLOB in a db. Any idea?
