Python email

[LutherRevisited]

I'm attempting to write an email client, and I've run into a snag. I've seen
several docs on email, but they're not dumbed down enough for me. Basically
I'm downloading my messages like this:
M = poplib.POP3('pop.mail.yahoo.com')
M.user('username')
M.pass_('password')
inMail = str(M.retr(i))
and I get the message just fine, but I want to pull out of all that just the
html part. How can I do this.

I get the message just fine, but I want to pull out of all that just the
html part.  How can I do this.

The email and email.Iterators modules offer methods for doing this. For
example:

***************************************************************
# Warning: untested code
import email
from email.Iterators import typed_subpart_iterator

inMail = derived_from_POP3_magic()
my_email = email.message_as_string(inMail)
html_parts = typed_subpart_iterator(my_email, 'text', 'html')

***************************************************************
You may also want to look at email.Iterators.body_line_iterator, useful for
bypassing the headers in each part of the email.

I have no idea what this derived from POP3Magic thing is, can you give me more
on that. I've begun to familiarize myself with the methods in email, but my
big snag seems to be that I get a single string that I can't manipulate with
these methods from what should be a multi-part message.

I still want to know about that POP3Magic thing, but I finally got this
working. I couldn't figure out why until just now. First I made sure I
retrieved the message as a list, then I iterated through it and concantenated
all that together into a string. Then I cast that as an email object. I
couldn't get the subsomething iterator thing to work, but I was able to walk
through it and check each part for content type. If anyone's interested here's
my code I used to test to see that this actually worked:
for x in M.retr(i)[1]:
stringMail += x
stringMail += '\n'
inMail = email.message_from_string(stringMail)
for part in inMail.walk():
if part.get_content_type() == 'text/html':
print part
