How to read a text file into a list or an array with Python

You will have to split your string into a list of values using split()

So,

lines = text_file.read().split(',')

EDIT: I didn’t realise there would be so much traction to this. Here’s a more idiomatic approach.

import csv
with open('filename.csv', 'r') as fd:
    reader = csv.reader(fd)
    for row in reader:
        # do something
