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
