[colug-432] Code check

[Tom Hanlon]

Colug,

If I have to write much more python, I will subscribe to the other lists.

But one more question

I have this snippet of borrowed code.

def showPayload(msg):
    payload = msg.get_payload()

    if msg.is_multipart():
        div = ''
        for subMsg in payload:
            print div
            showPayload(subMsg)
            div = '------------------------------'
    else:
        print msg.get_content_type()
        print payload[:200]



I am parsing a mbox file, and the above code works.

What goes to stdout is exactly what I want. However I want to capture it to
a variable.

This however does not work.

def showPayload2(msg):
    message_content = ""
    payload = msg.get_payload()

    if msg.is_multipart():
        div = ''
        for subMsg in payload:
            message_content += div
            showPayload2(subMsg)
            div = '------------------------------'
    else:
        message_content +=  msg.get_content_type()
        message_content += payload[:200]

    return [message_content]


showPayload2 only ever returns..
['------------------------------']


Here is the code with the working function showPayload, and my attempt to
capture to string instead of print to out, in showPayload2.

Am I missing something quick and simple to capture what is emitted to
stdout to a variable ? Or how do I do a recursive function call without
blowing away changes to the string ?

#!/usr/bin/python
import mailbox

def showPayload(msg):
    payload = msg.get_payload()

    if msg.is_multipart():
        div = ''
        for subMsg in payload:
            print div
            showPayload(subMsg)
            div = '------------------------------'
    else:
        print msg.get_content_type()
        print payload[:200]


def showPayload2(msg):
    message_content = ""
    payload = msg.get_payload()

    if msg.is_multipart():
        div = ''
        for subMsg in payload:
            message_content += div
            showPayload2(subMsg)
            div = '------------------------------'
    else:
        message_content +=  msg.get_content_type()
        message_content += payload[:200]

    return [message_content]

mbox = mailbox.mbox('201308.mbox')
for message in mbox:
    data = {}
    data['From']    = message['from']
    data['Subject']     = message['subject']
    data['Date'] = message['date']
    data['Content']   = showPayload2(message)
    print data
    showPayload(message)
    print showPayload2(message)
