Basically, this is a file called firesideResults , which i open in my code and i have to check through it. If the win column contains a 0 i do not print it out, so if it contains a number other than zero i display it on the screen. However, i have multiple lists of numbers to deal with and i can't find how to only deal with one column of numbers.

my code was going to be

if option == ("C") or option == ("c"):
    answer = False
    file_3 = open("firesideResults.txt")
    for column in file_3:
        if ("0" not in column):
            print(column)

But unfortunately, one of the other columns of code contain a 0 so i cannot do that. Thank you for your help and if possible please list any questions that i could check for help as i have been searching for so long.

Since you have comma-separated fields, the best way would be to use csv !

import csv

with open("firesideResults.txt") as file_3:
    cr = csv.reader(file_3)
    for row in cr:
        if row[2]!="0":
            print(row)

if third column of each row is not 0, then print it.

• no substring issue: checks for exact field
• checks for field at the "win" column only, not the other ones.
