Python 2.7：在写入文件时，“ ascii”编解码器无法编码字符u'xe9'错误 [英] Python 2.7: 'ascii' codec can't encode character u'\xe9' error while writing in file

问题描述

我知道这个问题已经被问了好几次了，但是不知何故我没有得到结果。

I know this question have been asked various time but somehow I am not getting results.

我正在从包含字符串Elzéar。在读入CSV文件时，它会给出问题标题中提到的错误。

I am fetching data from web which contains a string Elzéar. While going to read in CSV file it gives error which mentioned in question title.

在生成数据时，我做了以下操作：

While producing data I did following:

address = str(address).strip()
        address = address.encode('utf8')
        return name+','+address+','+city+','+state+','+phone+','+fax+','+pumps+','+parking+','+general+','+entertainment+','+fuel+','+resturants+','+services+','+technology+','+fuel_cards+','+credit_cards+','+permits+','+money_services+','+security+','+medical+','+longit+','+latit

并将其写为：

with open('records.csv', 'a') as csv_file:
  print(type(data)) #prints <unicode>
  data = data.encode('utf8')     
  csv_file.write(id+','+data+'\n')
  status = 'OK'
  the_file.write(ts+'\t'+url+'\t'+status+'\n')

产生错误，例如：

'ascii'编解码器无法在位置55编码字符u'\xe9'：序号
不在范围内（128）

'ascii' codec can't encode character u'\xe9' in position 55: ordinal not in range(128)

推荐答案

您可以尝试类似（python2.7） ：

You could try something like (python2.7):

#! /usr/bin/env python
# -*- coding: utf-8 -*-
import codecs
...
with codecs.open('records.csv', 'a', encoding="utf8") as csv_file:
  print(type(data)) #prints <unicode>
  # because data is unicode

  csv_file.write(unicode(id)+u','+data+u'\n')
  status = u'OK'
  the_file.write(unicode(ts, encoding="utf8")+u'\t'+unicode(url, encoding="utf8")+u'\t'+status+u'\n')

主要思想是尽可能多地使用unicode并在输出时返回str（最好不要在str上操作）。

The main idea is to work with unicode as much as possible and return str when outputing (better do not operate over str).
