CSV Read.

CSV is a table in text. Fields may contain commas inside quotes — so do not split(",").

import csv with open("items.csv", encoding="utf-8", newline="") as f: reader = csv.DictReader(f) total = 0 for row in reader: total += int(row["qty"]) print(total)

DictReader yields a dict per row; keys come from the header row. newline="" is recommended for csv.
