IndexError: List index out of range, only when performing operations 2 list items - Python -


i have following code:

infile = open("sitin.txt", "r") r = int(infile.readline().split()[0]) s = int(infile.readline().split()[1]) totalseats = r * s print(totalseats)

my input file, "sitin.txt" text file nothing 10 10. printing either r or s returns correct value, , printing either r or s multiplied 10 returns correct value, code, attempting multiply r , s returns "indexerror: list index out of range". happening here?

you read input file many times; r first line; s second line (and on)... fix:

infile = open("sitin.txt", "r") split = infile.readline().split()  # read once only! r = int(split[0]) s = int(split[1]) totalseats = r * s print(totalseats)

you may need check split has correct form input.
