My code is:

import csv def internet_histogram(): count_6 = 0 count_5 = 0 count_4 = 0 count_3 = 0 count_2 = 0 count_1 = 0 with open("survey.csv",'r') as f: reader = csv.reader(f) with open("histogram.csv", 'w') as g: writer = csv.writer(g) next(reader) for line in reader: if int(line[3]) >= 28 and int(line[3])  
However, i got a error feedback said:
 
function internet_histogram incorrect on input []
