Answer

file = open("marks.txt", "a")
running=1
while (running ==1) :
    indexNo = raw_input("Enter Index No: ") 
    if (indexNo=="-1"):
        running=-1
    else :
        mark1 = raw_input("Enter marks 1: ") 
        mark2 = raw_input("Enter marks 2: ") 
        mark3 = raw_input("Enter marks 3: ") 
        str=indexNo + "," + mark1 +  "," + mark2 +  ","  + mark2 + "\n"
        file.write (str)
file.close()
