msg.walk()

[Samuel Wright]

Hi Guys

Using Python 2.3 here, trying to parse a MBOX email file using the code below:

------------------------

mailboxfile = 'emails.txt'

import email
import email.Errors, email.Parser, email.Message
import mailbox

def msgfactory(fp):
try:
return email.message_from_file(fp)
except email.Errors.MessageParseError:
# Don't return None since that will
# stop the mailbox iterator
return ''


def main():
fp = open(mailboxfile, 'r')
mbox = mailbox.UnixMailbox(fp, msgfactory)
for msg in mbox:
print msg
for part in msg.walk():
print part

if __name__=="__main__":
main()

Using Python 2.3 here, trying to parse a MBOX email file using the

[...]

Notice the return ''

def main():
fp = open(mailboxfile, 'r')
mbox = mailbox.UnixMailbox(fp, msgfactory)
for msg in mbox:
print msg
for part in msg.walk():
print part

You have to do a test for an empty string in your main method (like the docs say).

"Notice the return ''"

def main():
fp = open(mailboxfile, 'r')
mbox = mailbox.UnixMailbox(fp, msgfactory)
for msg in mbox:
print msg
for part in msg.walk():
print part
[...]

"You have to do a test for an empty string in your main method (like

Gotcha. I had assumed that was for mailboxes that might not be well
formatted, and I was checking a mailbox I had exported myself...

Thanks loads.
