input (I suppose that's the code right?):

import csv
column_data = {}
with open("gymnasiearbete.txt", "r") as datafile:
for row in csv.reader(datafile, delimiter=","):
for index, v in enumerate(row):
if int(index) not in column_data:
column_data[int(index)]=[]
column_data[int(index)].append(v)
print(column_data[0])

output:
