Python Json 解析器[关闭]

我有一个具有以下结构的 JSON 文件：-

    "truncated": false, 
    "text": "@HomeShop18 #DreamJob to professional rafter",

} 

该文件中有近 1500 个此类词典。我想知道Python中是否有任何预先存在的解析器，用于这样的文件，用于延迟解析。我希望所述解析器一次只返回一本字典，或者，最坏的情况下，逐行返回数据。我应该怎么办？

这是一个解决方法函数使用json.JSONDecoder.raw_decode。我希望有人提出更好的方法来处理这个问题。

import json
import re

nonspace = re.compile(r'\S')
def iterparse(j):
    decoder = json.JSONDecoder()
    pos = 0
    while True:
        matched = nonspace.search(j, pos)
        if not matched:
            break
        pos = matched.start()
        decoded, pos = decoder.raw_decode(j, pos)
        yield decoded

用法示例：

>>> j = '''
... { "id": 1 }
... { "id": 2 }
... '''
>>> list(iterparse(j))
[{u'id': 1}, {u'id': 2}]
