How to iterate through file line by line? - python-2.7

Question

I have files with lines of input which I compare to eachother. I have simplified my code alot and obviously it isnt in working python but the main bits of important are the first line for iteration and the else clause, both of which are the ones used. The rest are just to show I wish to continue on with the data if it passes the Comparison code.
for read1, read2 in itertools.izip(input_file1, input_file2):
{CODE FOR COMPARISON}
if matched:
Worked = read1+read2
else:
print to output_file2
break
{CONTINUE ANALYSIS OF 'Worked'}
print Worked to output_file1
I assumed adding a print to file and break would solve the issue however it doesn't break the for loop so the next iteration occurs, it just breaks it. Is there anyway to use a command like break to move onto the next iteration of lines in both input files?
Thanks,
Tom

You are looking for the continue statement rather than the break statement:
break exits the loop whereas continue just moves onto the next iteration
for read1, read2 in itertools.izip(input_file1, input_file2):
{CODE FOR COMPARISON}
if matched:
Worked = read1+read2
else:
print to output_file2
continue
{CONTINUE ANALYSIS OF 'Worked'}
print Worked to output_file1
