Looking at it in Notepad++ I see "BUILDING DATA:(LF)"

Full Code

lines = open('scan.txt','r').readlines()
for a in lines:
    if re.search(r"Ad", a):
        digits = a
        if re.search(r"2013", digits):
            date.append(digits[:19])
            count +=1
        elif re.search(r",", digits):
            clean = digits.rstrip()
            sector = clean.split(',')
            x.append(sector[0])
            y.append(sector[1])
    elif re.search(r"CONTROLLED BY:", a):
        player.append(a[15:].rstrip())
    elif re.search(r"ALLIANCE:", a):
        alliance.append(a[10:].rstrip())
    elif re.search(r"SIZE:", a):
        size.append(a[6:].rstrip())
    elif re.findall('BUILDING DATA:sN/A', a, re.M):
        def_grid = ''
        print "Didn't find it"
        defense.append(def_grid)
        defense_count +=1
    elif re.search(r"DEFENSE GRID", a):
        def_grid = a[16:].rstrip()
        print "defense found"
        defense_count +=1

But I am not having anything returned.

I need to put an empty spacer in when "DEFENSE GRID" doesn't exist after "BUILDING DATA:"

I know i'm missing something and I've tried reading up on re.search but i'm not able to find any thorough examples that explain how the multiline works.

Answer 1

re.findall("BUILDING DATA:
N/A",a,re.MULTILINE)
