Question

我正在尝试使用以下权限阅读Google工作表文档：

    opener = urllib2.build_opener()
    opener.addheaders = [('Accept-Charset', 'utf-8')]
    response = opener.open(
       "https://docs.google.com/spreadsheets/d/ID/export?format=csv"
    )
    csv_records = unicodecsv.reader(response, encoding='utf-8')
    translations = csv.DictReader(csv_records) 
    for row in translations:
       print row["age"]

然而，我收到一个错误：expected string or Unicode object, list found可能是字段名。

出了什么问题？

堆栈跟踪：

  File "/Users/me/projects/ad_copy.py", line 68, in create_copies
    for row in translations
  File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/csv.py", line 107, in next
    self.fieldnames
  File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/csv.py", line 90, in fieldnames
    self._fieldnames = self.reader.next()
TypeError: expected string or Unicode object, list found

打印

print translations
print csv_records
<csv.DictReader instance at 0x11163fa28>
<unicodecsv.py2.UnicodeReader object at 0x11160da50>

Answer 1

据我了解，unicodecsv会返回一个列表，在您的情况下为csv_records。

这取自github README：

>>> import unicodecsv as csv
>>> from io import BytesIO
>>> f = BytesIO()
>>> w = csv.writer(f, encoding='utf-8')
>>> _ = w.writerow((u'é', u'ñ'))
>>> _ = f.seek(0)
>>> r = csv.reader(f, encoding='utf-8')
>>> next(r) == [u'é', u'ñ']
True

最后查看比较结果。

您将此返回的列表放入csv.DictReader()，这是不必要的，因为结果已经在csv_records内。

打印出这个变量，看看里面是什么。

DictReader错误：预期的字符串或Unicode对象，找到列表
