Question

我的Python脚本通过urllib2打开一个文件;数据如下所示：

"Charitable Donation: Contribution","012","","","","","","","","","","","","","","","","","","","",""

Python脚本：

reader = csv.reader(data, delimiter=',', quotechar='"', quoting=csv.QUOTE_ALL)
for row in reader:
    print row

输出是这样的：

['Charitable Donation: Contribution']
['', '']
['012']
['', '']
['']
['', '']
['']
['', '']
['']
['', '']
['']
['', '']
['']
['', '']
['']
['', '']
['']
['', '']
['']
['', '']
['']

我做错了什么？

Answer 1

你使用双引号（"）作为分隔符而不是逗号（,）... 为什么？怎么样

reader = csv.reader(data, delimiter=',', quoting=csv.QUOTE_ALL)
for row in reader:
    print row

# you can omit the delimiter argument as well, since comma is the default:
reader = csv.reader(data, quoting=csv.QUOTE_ALL)
# etc.

Answer 2

您希望逗号是分隔符，因为分隔符是分隔值的内容。 quotechar是“因为它包含的是什么值。

尝试

reader = csv.reader(data, delimiter=',',quotechar='"', quoting=csv.QUOTE_ALL)

Answer 3

第一个参数是迭代器。在示例here中，它们使用文件对象。迭代一个字符串会给出每个字符，但是你只想要这一行。最简单的解决方法是使data成为一个列表。

reader = csv.reader([data])
for row in reader:
    print row

它给出了输出：

['Charitable Donation: Contribution', '012', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '']

Answer 4

我认为你使用了错误的分隔符 - 你应该使用','然后注意你引用的部分被引用的事实。
