Emails with attachments produce errors

[clay4shin]

Hello, I'm following the book <Automate the Boring Stuff with Python> (Thank you for the amazing book, btw!) for ezgmail module.

I'm having an issue when I search emails with attachments and try to download it. The module seems to be able to search correct emails and save it to a thread object but when I try to read the summary of threads (ezgmail.summary(threads)) or try to access the attachments (threads[0]messages[0].attachments), it's showing me errors.

These are the codes and outputs I received from the terminal:

>>> import ezgmail
>>> threads = ezgmail.search('(now with attachment)')
>>> len(threads)
3
>>> ezgmail.summary(threads)
Traceback (most recent call last):

If you are searching for emails with attachments then you are using the wrong gmail search syntax. If you want it to find emails that have attachments to them use threads = ezgmail.search('has:attachment') instead of threads = ezgmail.search('(now with attachment)'). I suggest using the search options, on the right in the search bar (see image below), in gmail to get an accurate search syntax.
