在python中用引号解析逗号分隔的csv文件

Question

下面有一个字符串，表示从csv文件中提取的一行。每列用逗号分隔，值用“”括起来。在python中，解析每个列的值的最简单方法是什么？

"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"

上面的数据都是一个大字符串，需要拆分成列，这样我才能得到值。我不是在问如何加载csv文件。已经弄清楚了。

Python有一个模块：

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))
