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
base64 module is more compact if there are many such
characters, as when sending a graphics file.
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''.
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.
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().
