: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=False)
|
|
|
|
Decode the contents of the *input* file and write the resulting decoded binary
|
|
data to the *output* file. *input* and *output* must be :term:`file objects
|
|
<file object>`. *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, header=False)
|
|
|
|
Encode the contents of the *input* file and write the resulting quoted-printable
|
|
data to the *output* file. *input* and *output* must be :term:`file objects
|
|
<file object>`. *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`. *header* is a flag
|
|
which controls if spaces are encoded as underscores as per :rfc:`1522`.
|
|
|
|
|
|
.. function:: decodestring(s, header=False)
|
|
|
|
Like :func:`decode`, except that it accepts a source string and returns the
|
|
corresponding decoded string.
|
|
|
|
|
|
.. function:: encodestring(s, quotetabs=False, header=False)
|
|
|
|
Like :func:`encode`, except that it accepts a source string and returns the
|
|
corresponding encoded string. *quotetabs* and *header* are optional
|
|
(defaulting to ``False``), and are passed straight through to :func:`encode`.
