This module handles the content transfer encoding method defined in RFC 2045 to encode US ASCII-like 8-bit data called `quoted-printable'. It is used to safely encode text that is in a character set similar to the 7-bit US ASCII character set, but that includes some 8-bit characters that are normally not allowed in email bodies or headers. Quoted-printable is very space-inefficient for encoding binary files; use the email.base64mime module for that instead. This module provides an interface to encode and decode both headers and bodies with quoted-printable encoding. RFC 2045 defines a method for including character set information in an `encoded-word' in a header. This method is commonly used for 8-bit real names in To:/From:/Cc: etc. fields, as well as Subject: lines. This module does not do the line wrapping or end-of-line character conversion necessary for proper internationalized headers; it only does dumb encoding and decoding. To deal with the various line wrapping issues, use the email.header module. body_decode body_encode body_lengthdecode decodestring header_decode header_encode header_lengthquoteunquoteN) ascii_lettersdigits hexdigitsz  cCsg|] }d|qS)z=%02X).0crr"/usr/lib64/python3.6/quoprimime.py 7srs-!*+/ascii_ s_ !"#$%&'()*+,-./0123456789:;<>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~ cCst|t|kS)z>Return True if the octet should be escaped with header quopri.)chr_QUOPRI_HEADER_MAP)octetrrr header_checkJsrcCst|t|kS)z^sz header_length..)sum) bytearrayrrrrTs cCstdd|DS)zReturn a body quoted-printable encoding length. :param bytearray: An array of bytes (a.k.a. octets). :return: The length in bytes of the byte array when it is encoded with quoted-printable for bodies. css|]}tt|VqdS)N)r r)rrrrrr!hszbody_length..)r")r#rrrrascCsft|tst|}|s&|j|jnn^|d|kr||dtkr||dtkr|t|||d7}|d7}n||7}|d7}||kr>||7}q>WqW|d dkr|j|r|dd }|S) z_Decode a quoted-printable string.
