Hello

I have this input .txt file (a demo of it here, on a small scale) that after running the Python 3.6 code it should write in the input the following output (please see the output interleaved with #):

Output:
Noclue
*Title Test
12125
124125
asdas 1 1 1 1 
rthtr 1 1 1 1 
asdasf 1 1 1 1 
asfasf 1 1 1 1 
blabla 1 1 1 1 
#Expected "*Title Test2" here
124124124
*Title Dunno
12125
124125
12763125 1 1 1 1 
whatever 1 1 1 1
#Expected "*Title Dunno2" here
214142122

#and so on for thousands of them..

I have this code, that I have to adapt:

index = 0
insert = False
currentTitle = ""
testfile = open("test.txt","r")    
content = testfile.readlines()
finalContent = content
testfile.close()
# Should change the below line of code I guess to adapt
#titles = ["TitleX","TitleY","TitleZ"]   

for line in content:
    index = index + 1
    for title in titles:
        if line in title+"\n":    
            currentTitle = line
            print (line)
    if line == "1 1 1 1\n":
        insert = True
    if (insert == True) and (line != "1 1 1 1\n"):
        finalContent.insert(index-1, currentTitle[:6] + "2" + currentTitle[6:])
        insert = False

f = open("test.txt", "w")
finalContent = "".join(finalContent)
f.write(finalContent)
f.close()

Any help on how to adapt the above code to display the desired output would be more than appreciated!
Thanks!

1. read input line
   
2. write line to output
   
3. If this is target line, write new data
   
4. Continue loop at step 1 until finished, but eliminate step 3
