Using python for checking imap mailbox unread message

TurnToJPG -->

Just paste some python scripts:

>>> import imaplib
>>> obj=imaplib.IMAP4_SSL('imap.163.com','993')
>>> obj.login('XXXXX','XXXXXXXX')
('OK', [b'LOGIN completed'])
>>> obj.select()
('OK', [b'49'])
>>> obj.search(None,'Unseen')
('OK', [b''])
>>> len(obj.search(None, 'UnSeen')[1][0].split()) 
0
>>> len(obj.search(None, 'UnSeen')[1][0].split()) 
1
>>> len(obj.search(None, 'UnSeen')[1][0].split()) 
2
>>> len(obj.search(None, 'UnSeen')[1][0].split()) 
2
>>> len(obj.search(None, 'UnSeen')[1][0].split()) 
1
>>> 

Using the unread counts, you could easily interact with some other programs, for example shining LEDs.
