Function guess_type

Lib/mimetypes.py:322–342

Guess the type of a file based on its URL. Return value is a tuple (type, encoding) where type is None if the type can't be guessed (no or unknown suffix) or a string of the form type/subtype, usable for a MIME Content-type header; and encoding is None for no encoding or the name of

(url, strict=True)

    encoding is None for no encoding or the name of the program used
    to encode (e.g. compress or gzip).  The mappings are table
    driven.  Encoding suffixes are case sensitive; type suffixes are
    first tried case sensitive, then case insensitive.

    The suffixes .tgz, .taz and .tz (case sensitive!) are all mapped
    to ".tar.gz".  (This is table-driven too, using the dictionary
    suffix_map).

    Optional 'strict' argument when false adds a bunch of commonly found, but
    non-standard types.
