Question

我目前有这个解析imdbAPI http的代码返回：

text = 'unicode: {"Title":"The Fountain","Year":"2006","Rated":"R","Released":"22 Nov 2006","Genre":"Drama, Romance, Sci-Fi","Director":"Darren Aronofsky","Writer":"Darren Aronofsky, Darren Aronofsky","Actors":"Hugh Jackman, Rachel Weisz, Sean Patrick Thomas, Ellen Burstyn","Plot":"Spanning over one thousand years, and three parallel stories, The Fountain is a story of love, death, spirituality, and the fragility of our existence in this world.","Poster":"http://ia.media-imdb.com/images/M/MV5BMTU5OTczMTcxMV5BMl5BanBnXkFtZTcwNDg3MTEzMw@@._V1_SX320.jpg","Runtime":"1 hr 36 mins","Rating":"7.4","Votes":"100139","ID":"tt0414993","Response":"True"}'

def stripData(tag="Title"):
    tag_start = text.find(tag)
    data_start = tag_start + len(tag)+3
    data_end = text.find('"',data_start)
    data = text[data_start:data_end]
    return tag, data

我想知道：有没有更好的方法来解决这个问题？

>>> ast.literal_eval(text.split(' ', 1)[1])
{'Plot': 'Spanning over one thousand years, and three parallel stories, The Fountain is a story of love, death, spirituality, and the fragility of our existence in this world.', 'Votes': '100139', 'Rated': 'R', 'Response': 'True', 'Title': 'The Fountain', 'Poster': 'http://ia.media-imdb.com/images/M/MV5BMTU5OTczMTcxMV5BMl5BanBnXkFtZTcwNDg3MTEzMw@@._V1_SX320.jpg', 'Writer': 'Darren Aronofsky, Darren Aronofsky', 'ID': 'tt0414993', 'Director': 'Darren Aronofsky', 'Released': '22 Nov 2006', 'Actors': 'Hugh Jackman, Rachel Weisz, Sean Patrick Thomas, Ellen Burstyn', 'Year': '2006', 'Genre': 'Drama, Romance, Sci-Fi', 'Runtime': '1 hr 36 mins', 'Rating': '7.4'}

Answer 2

您可以在删除所有不必要的头部和尾部字符后尝试将所有数据转换为dict。

import re

line = 'unicode: {"Title":"The Fountain","Year":"2006","Rated":"R","Released":"22 Nov 2006","Genre":"Drama, Romance, Sci-Fi","Director":"Darren Aronofsky","Writer":"Darren Aronofsky, Darren Aronofsky","Actors":"Hugh Jackman, Rachel Weisz, Sean Patrick Thomas, Ellen Burstyn","Plot":"Spanning over one thousand years, and three parallel stories, The Fountain is a story of love, death, spirituality, and the fragility of our existence in this world.","Poster":"http://ia.media-imdb.com/images/M/MV5BMTU5OTczMTcxMV5BMl5BanBnXkFtZTcwNDg3MTEzMw@@._V1_SX320.jpg","Runtime":"1 hr 36 mins","Rating":"7.4","Votes":"100139","ID":"tt0414993","Response":"True"}'

def parser(text):
    match = re.search(r'\{\"([^}]+)\"\}', text)
    if match:
        return dict(x.split('":"') for x in match.group(1).split('","'))

newdict = parser(line)

for k, v in newdict.items():
    print k, v

我使用了正则表达式，但它很容易用在检索到的字符串中删除{“和之后}”的任何方法替换。

Answer 3

在我看来，每个人都在努力工作......如果你真的有

line = 'unicode: {"key1":"Value1", "key2","value2", etc...}'

它看起来像字符串 ...

然后从字符串前面删除“unicode：”

newline = line[9:]

然后将结果直接评估为dict

data_dict=eval(newline)

然后您按键

访问数据

print(data_dict['Title'])

您可以使用完美的格式来创建Python dict，并且可以直接从该容器访问这些值。
