python - parsing email_message['Subject'] results 3 strings instead of 1 -

i'm parsing email subject , getting multiple strings (depending on subject length) starting =?utf-8?b?. normal behavior? how can join strings 1 string 1 encoding?

email_message = email.message_from_string(raw_email) print email_message['subject'] 

...

=?utf-8?b?15bxkneqiner15pxmden15qg15hxodez16hxmdeqiner15vxk9ezinec15txkdez158g?=  =?utf-8?b?157xk9ev16ig15txp9ez15pxldetineu15bxlcdxnneqinei15xxkdetineq150g15dxonezineo15u=?=  =?utf-8?b?16nxnsdxlneo15hxla==?= 

edit:

subjectdecoded, encoding = decode_header(email.utils.parseaddr(email_message['subject'])[1])[0] if encoding==none:     subjectdecodedparsed = email_message['subject']     print 'i not decoding subject'     print subjectdecodedparsed else:     subjectdecodedparsed = subjectdecoded.decode(encoding)     print 'i decoding subject'     print subjectdecodedparsed.encode('utf8') #<--- first line presented here 

your string encoded using quoted-printable format mime headers. email.header module handles you:

>>> subject = '''\ ... =?utf-8?b?15bxkneqiner15pxmden15qg15hxodez16hxmdeqiner15vxk9ezinec15txkdez158g?= ...  =?utf-8?b?157xk9ev16ig15txp9ez15pxldetineu15bxlcdxnneqinei15xxkdetineq150g15dxonezineo15u=?= ...  =?utf-8?b?16nxnsdxlneo15hxla==?=''' >>> email.header import decode_header >>> line in subject.splitlines(): ...     bytes, encoding = decode_header(line)[0] ...     print bytes.decode(encoding) ...  זאת בדיקה בסיסית בכדי להבין  מדוע הקידוד הזה לא עובד אם אני רו שם הרבה 

the subject (which one string newlines , leading whitespace) spans multiple lines fit strict line length limitations set mime standard.
