Hi, I am using both xreadlines and files iterators for a script that I need to finish. I am iterating over the entire file but stopping to use xreadlines to grab certain lines as strings to process them.
My question is how do I go to a previous line in the file? xreadlines has a file.next() statement that gives the next line, and I need a statement that gives me the previous line. My script has a loop that looks for a certain word then breaks the loop. But I need to go to the previous line before I break since the script uses that line (which gets processed). I'm sure there is an easier way to do this but since I am new to python and have spent a lot of time on this script I can't really go back and change a lot of things unless there is no possible way. Something like the example below. f.open("text.txt",'r') files = f.xreadlines() Name = "Section 1" for line in f: if Name in line: while x<20 field = files.next() if "2.6" in field: *****files.previousline()***** break x=x+1 Thanks, Brett -- http://mail.python.org/mailman/listinfo/python-list
