Python csv模块拆分字符串,而不仅仅是字段

当我运行此输入(保存为变量'line')时:

xsc_i,202,"House of Night",21,"/21_202"

通过csv阅读器:

for row in csv.reader(line):
    print row

它会分割字符串,而不仅仅是字段

['x']
['s']
['c']
['_']
['i']
['', '']
['2']
['0']
['2']
['', '']

等等

即使我明确设置了分隔符,它也会出现此行为:

csv.reader(line, delimiter=",")

它甚至将字符串视为数组,但我无法弄清楚为什么,我不能只用逗号分割,因为许多逗号都在输入中的""字符串中.

Python 2.7,如果重要的话.

第一个参数将csv.reader()是一个包含csv行的可迭代对象.在您的情况下,输入是一个包含单行的字符串(也是可迭代的).您需要将其括在line一个列表中:

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

演示:

>>> import csv
>>> line = 'xsc_i,202,"House of Night",21,"/21_202"'
>>> for row in csv.reader([line]):
...     print row
... 
['xsc_i', '202', 'House of Night', '21', '/21_202']
