Unfortunately, a raw rstrip() eats other whitespace that may be
important. I frequently get tab-delimited files, using the following
pseudo-code:
def clean_line(line):
return line.rstrip('\r\n').split('\t')
f = file('customer_x.txt')
headers = clean_line(f.next())
for line in f:
field1, field2, field3 = clean_line(line)
do_stuff()
if field3 is empty in the source-file, using rstrip(None) as you suggest
triggers errors on the tuple assignment because it eats the tab that
defined it.
I suppose if I were really smart, I'd dig a little deeper in the CSV
module to sniff out the "right" way to parse tab-delimited files.
It's so easy that don't doing that is just inexcusable lazyness :)
Your own example, written using the csv module:
import csv
f = csv.reader(open('customer_x.txt','rb'), delimiter='\t')
headers = f.next()
for line in f:
field1, field2, field3 = line
do_stuff()
