Yahoo email "search and destroy"!

[snippsat]

I named my script DeleteEmailFiles.py, not imap_tools.py

Ohh sorry i did read a little fast.
Do you have file named mailbox.py?
Search the only one you should have is in folder ...site-packages\imap_tools.
Rename or delete if you have an other mailbox.py

Test import as i said for command line.

>>> from imap_tools import MailBox, A
>>> # no error here

# Can access attributes of MailBox
>>> MailBox.email_message_class
<class 'imap_tools.message.MailMessage'>
