在Python中高效解析字符串

Question

我目前有这个代码解析imdbAPI http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做到这一点我失踪了？

>>> ast.literal_eval(text.split(' ', 1)[1])
