I have a huge report file with some data where i have to do some data processing on lines starting with the code "MLT-TRR"
For now i have extracted all the lines in my script that start with that code and placed them in a separate file. The new file looks like this- Rules.txt.

```
MLT-TRR                         Warning     C:\Users\Di\Pictures\SavedPictures\top.png  63   10   Port is not registered [Folder: 'Picture']

MLT-TRR                         Warning     C:\Users\Di\Pictures\SavedPictures\tree.png 315  10   Port is not registered [Folder: 'Picture.first_inst']

MLT-TRR                         Warning     C:\Users\Di\Pictures\SavedPictures\top.png  315  10   Port is not registered [Folder: 'Picture.second_inst']

MLT-TRR                         Warning     C:\Users\Di\Pictures\SavedPictures\tree.png 317  10   Port is not registered [Folder: 'Picture.third_inst']

MLT-TRR                         Warning     C:\Users\Di\Pictures\SavedPictures\top.png  317  10   Port is not registered [Folder: 'Picture.fourth_inst']

```

For each of these lines i have to extract the data that lies after "[Folder: 'Picture" If there is no data after "[Folder: 'Picture" as in the case of my first line, then skip that line and move on to the next line.
I also want to extract the file names for each of those lines- top.txt, tree.txt

I couldnt think of a simpler method to do this as this involves a loop and gets messier.
Is there any way out i can do this? extracting just the file paths and the ending data of each line.

```
import os
import sys
from os import path
import numpy as np

folder_path = os.path.dirname(os.path.abspath(__file__))
inFile1 = 'Rules.txt'
inFile2 = 'TopRules.txt'

def open_file(filename):
    try:
        with open(filename,'r') as f:
            targets = [line for line in f if "MLT-TRR" in line]
            print targets
        f.close()
        with open(inFile1, "w") as f2:
            for line in targets:
                f2.write(line + "\n")
        f2.close()

    except Exception,e:
        print str(e)
    exit(1)

if __name__ == '__main__':
    name = sys.argv[1]
    filename = sys.argv[1]
    open_file(filename)

```
