:mod:`quopri` --- Encode and decode MIME quoted-printable data ============================================================== .. module:: quopri :synopsis: Encode and decode files using the MIME quoted-printable encoding. .. index:: pair: quoted-printable; encoding single: MIME; quoted-printable encoding This module performs quoted-printable transport encoding and decoding, as defined in :rfc:`1521`: "MIME (Multipurpose Internet Mail Extensions) Part One: Mechanisms for Specifying and Describing the Format of Internet Message Bodies". The quoted-printable encoding is designed for data where there are relatively few nonprintable characters; the base64 encoding scheme available via the :mod:`base64` module is more compact if there are many such characters, as when sending a graphics file. .. function:: 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". .. function:: 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`. .. function:: decodestring(s[,header]) Like :func:`decode`, except that it accepts a source string and returns the corresponding decoded string. .. function:: encodestring(s[, quotetabs]) Like :func:`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 :func:`encode`. .. seealso:: Module :mod:`mimify` General utilities for processing of MIME messages. Module :mod:`base64` Encode and decode MIME base64 data
