File Parsing Question

[Zentrader]

Save the previous line in a variable if you want the previous line
only.
 for line in inp:
   # Perform some operations with line
    if condition something:
         print prev_line
         print line
         break
    # I need to go back one line and use that line value
--> prev_line = line

If you want to do more than that, then use data=inp.readlines() or you
can use
data = open(myfile), "r").readlines().  The data will be stored in
list format so you can access each line individually.
