: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
|
|
|
|
**Source code:** :source:`Lib/quopri.py`
|
|
|
|
--------------
|
|
|
|
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`.
