[Tutor] Incrementing a line?

[Jim Boone]

Howdy all, i hope this is the right list for my query, pythons a bit new 
to me, and I'm trying dto something that I can't figure out:

for s in userlog.readlines():
            for word in s.split():
                if word == ("19(Constraint"):
                    constraintlog.write(s + "\n")
                    print "\n\n*****Constraint Violations exist!!*****\n\n"
        constraintlog.close()

Is a section of code i have, it reads a log file and cranks out a log 
file on a certain condition, I can get it to write out the same line 
which is in the original log file, which is useful, but, what would be 
much more useful is if i could write out the line thats 10 lines after 
the "19(Constraint", because it's more pertinent, but of course s+10 is 
stupidly wrong.

Any help appreciated, Thanks!

The myth that Bill Gates has appeared like a knight in shining armor to lead all customers out of a mire of technological chaos neatly ignores the fact that it was he who, by peddling second-rate technology, led them into it in the first place, and continues to do so today.
