You want a dictionary, not an array.

mimetypedict = {}
for line in mimetypefile:
    line = line.rsplit('\r\n')
    extension, mimetype = line.split(':')
    mimetypedict[extension] = mimetype

Note that there's already a MIME type database in the standard mimtypes
module: <http://python.org/doc/current/lib/module-mimetypes.html>.
