The ``Hello, world'' of csv reading is
import csv
reader = csv.reader(open("some.csv", "rb"))
for row in reader:
print row
To print just the first and last columns of each row try
import csv
reader = csv.reader(open("some.csv", "rb"))
for row in reader:
print row[0], row[-1]
The corresponding simplest possible writing example is
import csv
writer = csv.writer(open("some.csv", "wb"))
for row in someiterable:
writer.writerow(row)
