You need to break out of the for loop.
The command to do that is 'break'
Just add a break on a line after the print
statement

I'm not sure I understand what you mean there.
If you break out of the loop you can still access
your loop variable. But I'm not sure what you mean
by "get the value of sublist[3] in another file."

Do you want to read another file and compare
it to sublist[3]?
Or do you want to put the value of sublist[3]
into another file?
