Reading one line of csv data in Python

There is a lot of examples of reading csv data using python, like this one:

import csv
with open('some.csv', newline='') as f:
  reader = csv.reader(f)
  for row in reader:
    print(row)

I only want to read one line of data and enter it into various variables. How do I do that? I've looked everywhere for a working example.

My code only retrieves the value for i, and none of the other values

reader = csv.reader(csvfile, delimiter=',', quotechar='"')
for row in reader:
  i = int(row[0])
  a1 = int(row[1])
  b1 = int(row[2])
  c1 = int(row[2])
  x1 = int(row[2])
  y1 = int(row[2])
  z1 = int(row[2])
