使用Python解析JSON

Question

我想解析一下

{"ticker":{"high":31.9099,"low":22.5,"vol":108468,"buy":29.61,"sell":30,"last":29.61}}

最后得到:

last = 29.61

但我不知道从哪里开始解析python :(

Answer 1

>>> text = '''{"ticker":{"high":31.9099,"low":22.5,"vol":108468,"buy":29.61,"sell":30,"last":29.61}}'''
>>> json.loads(text)
{u'ticker': {u'sell': 30, u'buy': 29.609999999999999, u'last': 29.609999999999999, u'vol': 108468, u'high': 31.9099, u'low': 22.5}}
>>> json.loads(text)[u'ticker'][u'last']
29.609999999999999

或者使用simplejson和旧版本的Python.
