Multipart email returning 0 for "is_multipart()"

I'm trying to parse a multi-part email but regardless of what I try, I cannot get my code to recognize any emails as multipart MIME messages.

The code is basically:

Code:

fp = open('C:\Python22\email.txt')
msg = email.message_from_file(fp)
fp.close()

for part in msg.walk():
    if part.is_multipart():
        print part.is_multipart()
    else:
        print part.is_multipart()

As a result I cannot seem to do anything to extract the attached .tif file, or even strip off the headers using either the rfc822 or email modules.

I'd love any help, I'm getting desparate.

The email I tried last is simple text email with a .tif attachment:

To my eyes it's clearly a multi-part MIME message with a .tif attachment, what am I missing?

try this

part.get_maintype() == 'multipart'

-----------
m.get_maintype(default=None)

Returns m's main content type, a string 'maintype' taken from header Content-Type converted to lowercase. When m has no header Content-Type, get_maintype returns default.

I'm just looking at your code and i have to say I'm a little unsure of what your doing with the if statment, even if multipart is false you still go and print the same data as if it were true, do yourself a favour and just print part.is_multipart()

Code:

fp = open('C:\Python22\email.txt')
msg = email.message_from_file(fp)
fp.close()

for part in msg.walk():
    print part.is_multipart()

You'll get the same result and use less code. less code == less for python to do == better preformance (in theory)

Mark.

Actually, I had some other stuff in the if/else statements that I removed for clarity's sake when posting. Otherwise I'd agree.
