12.7.1 MimeTypes Objects

`MimeTypes` instances provide an interface which is very like that of the `mimetypes` module.

`suffix_map`
  Dictionary mapping suffixes to suffixes. This is used to allow recognition of encoded files for which the encoding and the type are indicated by the same extension. For example, the .tgz extension is mapped to .tar.gz to allow the encoding and type to be recognized separately. This is initially a copy of the global `suffix_map` defined in the module.

`encodings_map`
  Dictionary mapping filename extensions to encoding types. This is initially a copy of the global `encodings_map` defined in the module.

`types_map`
  Dictionary mapping filename extensions to MIME types. This is initially a copy of the global `types_map` defined in the module.

`common_types`
  Dictionary mapping filename extensions to non-standard, but commonly found MIME types. This is initially a copy of the global `common_types` defined in the module.

`guess_extension`(type[, strict])
  Similar to the `guess_extension()` function, using the tables stored as part of the object.

`guess_type`(url[, strict])
  Similar to the `guess_type()` function, using the tables stored as part of the object.

`read`(path)
  Load MIME information from a file named path. This uses `readfp()` to parse the file.

`readfp`(file)
  Load MIME type information from an open file. The file must have the format of the standard mime.types files.
