How to read email using Python 3

Question

Now I am here

 import imaplib
 mail = imaplib.IMAP4_SSL('imap.gmail.com')
 mail.login('login@gmail.com', 'password')
 mail.list()
 # Out: list of "folders" aka labels in gmail.
 mail.select("inbox") # connect to inbox.
 #Get an email
 result, data = mail.uid('fetch', b'1', '(RFC822)')
    raw_email = data[0][1]
    email_message = email.message_from_bytes(raw_email)
    maintype = email_message.get_content_maintype()
    #HERE COMES TROUBLES - if hmtl will be base64 string
    if maintype == 'multipart':
        for part in email_message.get_payload():
            print(part.get_content_maintype())
            if part.get_content_maintype() == 'text':
                html = str(part.get_payload())
    elif maintype == 'text':
        html = str(email_message.get_payload())

    #Now I Can parse HTML
    if html is not None:
        soup = BeautifulSoup(html, 'html.parser')

some letters come with base64 coding. how decode it?
base64.b64encode(some_string) - doesn't help

Answer 1

import email

raw_email = data[0][1]
email_message = email.message_from_string(raw_email)

print email_message['To']

print email.utils.parseaddr(email_message['From']) # for parsing "Yuji Tomita" <yuji@grovemade.com>

print email_message.items() # print all headers


def get_first_text_block(self, email_message_instance):
maintype = email_message_instance.get_content_maintype()
if maintype == 'multipart':
    for part in email_message_instance.get_payload():
        if part.get_content_maintype() == 'text':
            return part.get_payload()
elif maintype == 'text':
    return email_message_instance.get_payload()
