Claws-mail - search for messages in date range

Claws-mail message search uses age in days to select messages by time, which is fine for "something more than two weeks ago but less than a month ago" (ag 14 & al 31) but not helpful for "a message in October 2010". This python script prints the Claws-mail extended search string for a given date range:

(replace raw_input with input for Python 3.x)

#!/usr/bin/python
import datetime
FROM = raw_input("From date YYYY-MM-DD: ")
TO = raw_input("To date YYYY-MM-DD: ")
FROM = datetime.datetime.strptime(FROM, "%Y-%m-%d")
TO = datetime.datetime.strptime(TO, "%Y-%m-%d")
NOW = datetime.date.today()
START = (NOW-FROM.date()).days
STOP = (NOW-TO.date()).days
print("al %d & ag %d" % (START, STOP-1))
