This is my current code. I want to check the two values(lines) to check for matches in the files.

def checkOS():
    fid1 = open("C:/Python/NSRLOS.txt", 'r')
    fid2 = open("C:/Python/sha_sub_hashes.out", 'r')
    outdata = open("osMatches.txt", 'w')
    line1 = fid1.readline()
    line2 = fid2.readline()
    while(line1 and line2):
        xline= line1.split(',')[1]
        yline = line2.split("|")[3]
        zline = xline.replace('"','')
        if (yline == zline):
            outdata.append([yline , zline])
            print xline, zline

if __name__=="__main__":
    checkOS()

The only problem is I’m not sure what I’ve written does that, all the code before the if statement is just reformatting to be able to pull from the index of the line. What I want to know is if the statement I used works in that sense and is it efficient? Then I want to output the equal values.
Here are some lines in the files:

Now you probably won’t find any immediate matches in these few lines, but I know that somewhere down the line there will be at least one match because I saw that while skimming through the files.

    you’re probably looking for something like this:

    use with() it automatically closes the files for you.

    def checkOS():
    with open("C:/Python/NSRLOS.txt") as fid1,open("C:/Python/sha_sub_hashes.out") as fid2,open("osMatches.txt", 'w') as outdata:
        for xline,yline in zip(fid1,fid2):  #zip fetches lines from both files one by one                                           
            xline= xline.split(',')[1]      #use itertools.izip instead of zip if you're on python 2.x
            yline = yline.split("|")[3]
            zline = xline.replace('"','')
            if yline == zline:                
                outdata.write("{0}{1}\n".format(yline , zline)) #use write to write the data back

if __name__=="__main__":
checkOS()
