How to read one single line of CSV data in Python?

There are 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?

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])
