przeanalizuj plik CSV oddzielony przecinkami z cytatami w pythonie

Question

Poniżej znajduje się ciąg znaków reprezentujący pojedynczy wiersz pobrany z pliku CSV. Każda kolumna jest oddzielona przecinkiem, a wartość jest zawijana w "". Jaki jest najprostszy sposób przeanalizowania wartości z każdej kolumny w pythonie?

"Mr","Bob","","Boberton","","President","","","","Blah, Inc. of Iowa","blah blah blah","","Grand Island","Hall County","NE","68801","7228","United States","308-111-1111","","","P.O. BOX 1111","","Grand Island","Hall County","NE","11111","1111","United States","","40.00000","-98.0000","Gasoline service stations","11111","1010101010","","","false","SINGLE_LOCATION","","","","","","","","","No","No","No","Owns","No","No","","","55.125905","","0.052369","","100","","100","0","","","1971","Low Risk","Convenience Stores & Truck Stops","1111111","1111111","111111","1111111" 

Powyższe dane to jeden duży ciąg, który należy podzielić na kolumny, aby uzyskać wartości. Nie pytam, jak załadować plik CSV. Już ta część została wymyślona.

Answer 1

Python ma moduł na to:

http://docs.python.org/library/csv.html

import csv, sys 
filename = 'some.csv' 
with open(filename, 'rb') as f: 
    reader = csv.reader(f) 
    try: 
     for row in reader: 
      print row 
    except csv.Error, e: 
     sys.exit('file %s, line %d: %s' % (filename, reader.line_num, e))
