18.15. "quopri" — Encode et décode des données *MIME quoted-printable*
**********************************************************************

**Code source :** Lib/quopri.py

======================================================================

Ce module effectue des encodages et décodages de transport *quoted-
printable*, tel que définis dans la **RFC 1521** : « *MIME
(Multipurpose Internet Mail Extensions) Part One Mechanisms for
Specifying and Describing the Format of Internet Message Bodies* ».
L’encodage *quoted-printable* est adapté aux données dans lesquelles
peu de données ne sont pas affichables. L’encodage *base64* disponible
dans le module "base64" est plus compact dans les cas où ces
caractères sont nombreux, typiquement pour encoder des images.

quopri.decode(input, output[, header])

   Decode the contents of the *input* file and write the resulting
   decoded binary data to the *output* file. *input* and *output* must
   either be file objects or objects that mimic the file object
   interface. *input* will be read until "input.readline()" returns an
   empty string. If the optional argument *header* is present and
   true, underscore will be decoded as space. This is used to decode «
   Q »-encoded headers as described in **RFC 1522**: « MIME
   (Multipurpose Internet Mail Extensions) Part Two: Message Header
   Extensions for Non-ASCII Text ».

quopri.encode(input, output, quotetabs)

   Encode the contents of the *input* file and write the resulting
   quoted-printable data to the *output* file. *input* and *output*
   must either be file objects or objects that mimic the file object
   interface. *input* will be read until "input.readline()" returns an
   empty string. *quotetabs* is a flag which controls whether to
   encode embedded spaces and tabs; when true it encodes such embedded
   whitespace, and when false it leaves them unencoded.  Note that
   spaces and tabs appearing at the end of lines are always encoded,
   as per **RFC 1521**.

quopri.decodestring(s[, header])

   Like "decode()", except that it accepts a source string and returns
   the corresponding decoded string.

quopri.encodestring(s[, quotetabs])

   Like "encode()", except that it accepts a source string and returns
   the corresponding encoded string.  *quotetabs* is optional
   (defaulting to 0), and is passed straight through to "encode()".
