I have two mbox files that I need to combine, merge or concat into one mbox file.

I've tried a for loop that pulls the messages into one master list but not sure if this is the best way since I now have two lists that can be combined but need a final mbox file(I suppose). I plan on again breaking down the combined mbox file into a data frame, which I've done for one mbox file already.

Here's what I have thus far:

inbox_1 = mailbox.mbox('Inbox1.mbox')
inbox_2 = mailbox.mbox('Inbox2.mbox')

all_msgs = []
for message in inbox_1:
    all_msgs.append(message)

for message in inbox_2:
    all_msgs.append(message)
#convert back to .mbox format

Any help would be appreciated. Thanks in advance!

    If they're true mbox files, and you're not sorting them, you could just 'cat' them together (potentially needing to insert a blank line). Python may be overkill! – Max Jun 03 '21 at 21:00
