If you're using the digest version, you should copy the subject line and 
simply add RE: in front of it (don't add "Tutor Digest, Vol. 69, Issue 
21 - ") to preserve threading in a threaded newsreader. If you want to 
change the subject line but keep the threading (often discussion drifts 
away from the original topic), you could copy the Message ID header 
(better idea, don't change the subject line unless you're using a 
threaded newsreaded)

an alternative could be to us str.replace:

from time import strftime

current_year = strftime("%Y")
current_month = strftime("%m")
current_day = strftme("%d")

def katt(date):
     date = date.replace("cyear", current_year)
     date = date.replace("cmonth", current_month)
     date = date.replace("cday", current_day)
     return map(int, date.split("_"))
