Oops, not quite right because it inserts colons blindly in the first field -
which appears not what you want.  More correct implementation in Python:

!/usr/bin/env python

import sys

for line in sys.stdin.readlines():

    line = line.strip().split()
    label = line[0]
    comment = " ".join(line[3:])
    print("%s    DC   %s+2    %s" %(label, label.replace(':', ''), comment))
