ascii编解码器无法编码字符，python 2.6

Question

我知道这是一个常见的初学者问题，在堆栈交换中有大量这样的问题，我一直在搜索它们，但我仍然无法弄清楚。我有一些来自抓取的数据，看起来像这样（列表中大约有 1000 个项目）：

inputList = [[u'someplace', u'3901 West Millen Drive', u'Hobbs', u'NH', 
u'88240', u'37.751117', u'-103.187709999'], [u'\u0100lon someplace', u'3120 
S Las Vegas Blvd', u'Las Duman', u'AL', u'89109', u'36.129066', u'-145.168791']]

我正在尝试将其写入这样的 csv 文件：

for i in inputList:
    for ii in i:
        ii.replace(" u'\u2019'", "") #just trying to get rid of offending character
        ii.encode("utf-8")

def csvWrite(inList, outFile):
    import csv
    destination = open(outFile, 'w')
    writer = csv.writer(destination, delimiter = ',')
    data = inList   
    writer.writerows(data)
    destination.close()
csvWrite(inputList, output)

但我不断收到此错误，writer.writerows(data)：

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in  
position 5: ordinal not in range(128)

我尝试了很多不同的方法来对列表中的数据进行编码，但仍然总是出错。我愿意忽略无法编码为ascii的字符。谁能指出我正确的方向，我正在使用python2.6

Answer 1

这条线似乎很奇怪：ii.replace(" u'\u2019'", "")，你的意思是ii.replace(u"\u2019", u"") 吗？

Answer 2

如果您只是想删除那些坏字符，您可以使用以下代码：

for i in inputList:
    for ii in i:
        ii = "".join(list( filter((lambda x: ord(x) < 128), ii)))
        print ii

输出：

someplace
3901 West Millen Drive
Hobbs
NH
88240
37.751117
-103.187709999
lon someplace
3120 S Las Vegas Blvd
Las Duman
AL
89109
36.129066
-145.168791

最终代码将如下所示：

inputList = [[u'someplace', u'3901 West Millen Drive', u'Hobbs', u'NH', 
u'88240', u'37.751117', u'-103.187709999'], [u'\u0100lon someplace', u'3120 S Las Vegas Blvd', u'Las Duman', u'AL', u'89109', u'36.129066', u'-145.168791']]

cleared_inputList = []

for i in inputList:
    c_i = []
    for ii in i:
        ii = "".join(list( filter((lambda x: ord(x) < 128), ii)))
        c_i.append(ii)
    cleared_inputList.append(c_i)

def csvWrite(inList, outFile):
    import csv
    destination = open(outFile, 'w')
    writer = csv.writer(destination, delimiter = ',')
    data = inList   
    writer.writerows(data)
    destination.close()


csvWrite(cleared_inputList, output)
