在python中用引号解析逗号分隔的csv文件

下面我有一个字符串，它表示从csv文件中提取的一行。每列用逗号分隔，值用“”包装。在python中，从每一列中解析出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。我不是问如何加载csv文件。已经解决了这一部分。

Python有一个模块：

使用

csv

。事实上，在使用

csv

之前，请尝试在堆栈溢出中搜索解析csv的类似问题，因为所有这些问题都已经编写了代码示例。这很有帮助，但如何从特定列中获取值？@Sam:每行都是一个列表，每列有一个条目。@Sam:或者，csv模块有一个DictReader类，该类将使用app engine的blob_阅读器将数据读入DictI am解析csv文件。每一行都是一个字符串，所以基本上我想知道应该使用什么正则表达式来获取值。没关系。我能够用csv模块加载AppEngine给我的东西。

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))
