[Tutor] Conditional output of a header line

[Levy Lazarre]

Good afternoon all,

I have written a script that cleans an error log and
writes the output to a
new file. Basically, I read the file line by line,
apply various filters to
eliminate the trashy lines, and output the desired
lines to a new file via 
print statements. I am having some difficulty with one
last task however. 
I need to conditionally eliminate a header line
depending on what comes on
the next line. 
Please see the sample below. When a line starts with
"Console Log" I need to 
'look ahead' and see if it is followed by a time stamp
hh:mm:ss. If so, 
output it. If not suppress it. In the example
enclosed, I would want to output
the first "Console Log ..." line but ignore the second
one.  

Is there an easy way to do this in Python? Apparently
I can't use a regexp 
since I am reading line by line. All suggestions
(except coding a state
machine!) will be appreciated.

Thanks,
