# 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()`.
