How to delete letters automatically with imaplib?

[elearn]

I have a gmail account 'x...@gmail.com' which subscripted python 
maillist. To take part in python discussion is the only target for my 
x...@gmail.com. There are so many emails in my x...@gmail.com,it is a good 
idea for me to auto delete all emails whose body contain no . I write 
some codes to do the job.


|import  imaplib
user="xxx"
password="yy"
con=imaplib.IMAP4_SSL('imap.gmail.com')
con.login(user,password)
con.select('INBOX')
status,  data=  con.search(None,  "ALL")
print(len(data[0].split()))
48
typ,  data=  con.search(None,  'Body',  '"x...@gmail.com"')

 data

[b'1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29
 32 33 34 35 36 37 44']

len(data[0].split())
36|

How can i delete 48-36=12 letters?

Set operations are designed for this::

 # Construct a set of all message numbers.
 status, data = con.search(None, "ALL")
 ids_of_all_messages = set(data[0].split())

 # Construct a set of messages mentioning the address.
 status, data = con.search(None, 'Body', '"x...@gmail.com"')
 ids_of_messages_containing_address = set(data[0].split())

 # Get the messages to delete.
 ids_of_messages_to_delete = (
 ids_of_all_messages - ids_of_messages_containing_address)

more simple to split the string?

[elearn]

str='(\\HasNoChildren \\Junk) "/" "[Gmail]/&V4NXPpCuTvY-"'
x=str.split(' "')
[i.replace('"','') for i in x]
['(\\HasNoChildren \\Junk)', '/', '[Gmail]/&V4NXPpCuTvY-']

x.strip(" ") will create four parts.

is there more simple to do that ?
