Why does she append the header to the filtered_rows list?
from s3v1 import *
def filter_col_by_string(data_sample, field, filter_condition):
filtered_rows = []
col = int(data_sample[0].index(field))
filtered_rows.append(data_sample[0])
for item in data_sample[1:]:
if item[col] == filter_condition:
filtered_rows.append(item)
return filtered_rows
silk_ties = filter_col_by_string(data_from_csv, "material", "_silk")
print("Found {} silk ties".format(number_of_records(silk_ties)))
wool_ties = filter_col_by_string(data_from_csv, "material", "_wool")
print("Found {} wool ties".format(number_of_records(wool_ties)))
cotton_ties = filter_col_by_string(data_from_csv, "material", "_cotton")
print("Found {} cotton ties".format(number_of_records(cotton_ties)))
gucci_ties = filter_col_by_string(data_from_csv, "brandName", "_Gucci")
print("Found {} Gucci ties".format(number_of_records(gucci_ties)))
