Answer 1

it moves all the mail in a given gmail label to the gmail Trash

#!usr/bin/python
import email, imaplib

user = 'xxx'
pwd = 'xxx'

m = imaplib.IMAP4_SSL("imap.gmail.com")
m.login(user,pwd)

m.select("some_gmail_label")
m.store("1:*",'+X-GM-LABELS', '\\Trash')

m.expunge() # should be useless, but gmail server says it is ok

Remember to refresh your gmail interface cause it has cache
