Question

I have an input text file which I am reading and storing everything in a list. After that I’m splitting the list according to the specific text occurence in the list.

Here is the function.

import re
def readFile1(file1):
    f = file1.read().split('\n')
    #print f
    ctrlList1 = []
    mfcList1 = []

    for str in f:
        if re.search("MegaMon> mfc",str):
            print "splitting\n"
            break
        else:
            ctrlList1.append(str)

    print ctrlList1, "\n\n\n"

This works fine and saves ctrlList1 until the text megamon> mfc appears in the main list. But I want to save the lines after MegaMon> mfc in mfcList1. I am not able to do that.

I tried:

if not re.search("MegaMon> mfc", str):
   print "splitting\n"
   continue
else:
    mfcList1.append(str)

but this doesn’t seem to be working. I need to save the text file in two different lists. Any help would be appreciated.

how about

 import re
 mfcList1, ctrlList1 = [],[]
 # read the whole file as a list of lines - its easier
 with open(file1, 'r') as f1:
     lines = f1.readlines()

 # for each line, search for your string. 
 # If you have found MegaMon append one mfcList1, else append ctrlList1
 foundMegaMon = False
 for line in lines:
     if re.search("MegaMon> mfc",line):
          foundMegaMon = True
     if foundMegaMon:
          mfcList1.append(line)
     else:
          ctrlList1.append(line)
