How to read a CSV line with "?

Question

A trivial CSV line could be spitted using string split function. But some lines could have \", e.g.

\"good,morning\", 100, 300, \"1998,5,3\"
         


        

Answer 1

From python's CSV module:

reading a normal CSV file:

import csv
reader = csv.reader(open("some.csv", "rb"))
for row in reader:
    print row

Reading a file with an alternate format:

import csv
reader = csv.reader(open("passwd", "rb"), delimiter=':', quoting=csv.QUOTE_NONE)
for row in reader:
    print row

There are some nice usage examples in LinuxJournal.com.

If you're interested with the details, read "split string at commas respecting quotes when string not in csv format" showing some nice regexen related to this problem, or simply read the csv module source.
