Question

请原谅我丑陋的新代码，我正在学习。我从OMDB API中提取电影数据，但当我将其移动到CSV时，我会为许多电影获取UnicodeEncodeError。可能是因为演员姓名有重音符号。我想1.）确定哪些电影有问题，2。跳过它们，和/或3.）最好纠正错误。当错误发生时，我现在只传递整个事物。寻找一个简单的解决方案，因为我是新手。

import csv
import os
import json
import omdb

movie_list = ['A Good Year', 'A Room with a View', 'Anchorman', 'Amélie', 'Annie Hall', 'Before Sunrise']

data_list = []

textdoc = open('textdoc.txt','w')

for w in movie_list:
    x = omdb.request(t=w, fullplot=True, tomatoes=True, r='json')
    y = x.content
    z = json.loads(y)
    data_list.append([z["Title"], z["Year"], z["Actors"], z["Awards"], z["Director"], z["Genre"], z["Metascore"], z["Plot"], z["Rated"], z["Runtime"], z["Writer"], z["imdbID"], z["imdbRating"], z["imdbVotes"], z["tomatoRating"], z["tomatoReviews"], z["tomatoFresh"], z["tomatoRotten"], z["tomatoConsensus"], z["tomatoUserMeter"], z["tomatoUserRating"], z["tomatoUserReviews"]])

try:
    with open('Films.csv', 'w') as g:
        a = csv.writer(g, delimiter=',')
        a.writerow(["Title", "Year", "Actors", "Awards", "Director", "Genre", "Metascore", "Plot", "Rated", "Runtime", "Writer", "imdbID", "imdbRating", "imdbVotes", "tomatoRating", "tomatoReviews", "tomatoFresh", "tomatoRotten", "tomatoConsensus", "tomatoUserMeter", "tomatoUserRating", "tomatoUserReviews"])
        a.writerows(data_list)
except UnicodeEncodeError:
    print("fail")

Answer 1

Python 2.x：您可以尝试使用codecs代替with open("Films.csv", 'w') as g:，以便以UTF-8编码打开csv输出。

import codecs
with codecs.open('Films.csv', 'w', encoding='UTF-8') as g:
# rest of code

Python 3.x：尝试使用g编码打开UTF-8：

with open('Films.csv', 'w', encoding='UTF-8') as g:
# rest of code.

Answer 2

试用smart_str

from django.utils.encoding import smart_str
data_list.append(map(smart_str, [z['element1'], z['element2']]))
a.write_row(map(smart_str, ["Title", "Year", "Actors", "Awards", "Director", "Genre", "Metascore", "Plot", "Rated", "Runtime", "Writer", "imdbID", "imdbRating", "imdbVotes", "tomatoRating", "tomatoReviews", "tomatoFresh", "tomatoRotten", "tomatoConsensus", "tomatoUserMeter", "tomatoUserRating", "tomatoUserReviews"]))
a.write_rows(data_list)

Answer 3

如果使用Python 2，csvwriter并不真正支持Unicode，但csv文档中有一个示例可以解决它。一个例子是this answer。

如果使用Python 3，请进行以下更改：

y = x.content.decode('utf8')

和

with open('Films.csv', 'w', encoding='utf8',newline='') as g:

通过这些更改，文本将被解码为Unicode以便在Python脚本中进行处理，并在写入文件时编码回UTF-8。这是处理Unicode的推荐方法。

newline=''是打开csv使用文件的正确方法。请参阅this answer和csv文档。

您也可以删除try / except。它只是抑制了有用的追溯。

Answer 4

对我有用的解决方案是在导出过程的开头添加：

import sys
reload(sys)
sys.setdefaultencoding('utf8')

带有csv.writer的UnicodeEncodeError
