CVS how to split and find number of 0's in column : I have 14 columns (A-N) in a CVS file I am looking to to find how many patients(303 in total) have 0 signs for heart disease this would be in column 14(N) anything above 0 would be counted as ill patients and those with 0 are healthy.

From what I have in my code so far is this ( i know I am more than likely doing this wrong so please correct me if I made a mistake)

    import csv
    import math
    with open("train.csv", "r") as f:
    #HP is healthy patient IP is ill patients
        for c in f.read()14:
            chars.append(c)
    num_chars = len(chars)
    num_IP = 0;
    num_HP = 0;
    for c in chars:
        if c = >0
            num_IP += 1
        if c = <=0
            num_HP += 1
