Python 2.7 Python从文本行提取数据

我从一个网页上得到了以下信息。这应该有很多行，出现在[]中，从{“EffectiveTime”…到“SystemLoad”}我想从所有这些标记中提取值。。。有人能建议正确的方法吗？有这么多行及其重复出现

{"Debug":"Key:01-Oct-2016 04:00:00_04-Dec-2016 23:45:00,
Age:-1","ErrorMessage":null,"LastUpdated":"06-Dec-2016 15:14:14","Rows":
[{"EffectiveTime":"01-Oct-2016 
04:00:00","EurPrice":30.460,"GbpPrice":26.260,"RunType":"EP2","SystemLoad":2702.
651},{"EffectiveTime":"01-Oct-2016 
04:30:00","EurPrice":30.460,"GbpPrice":26.260,"RunType":"EP2","SystemLoad":2694.
620},{"EffectiveTime":"01-Oct-2016 
05:00:00","EurPrice":30.510,"GbpPrice":26.300,"RunType":"EP2","SystemLoad":2718.
430},

让我们从

[]

字符开始定义输入字符串（跳过调试部分）

它直接是json数据：未序列化为python字典列表

import json

text='''[{"EffectiveTime":"01-Oct-2016 04:00:00","EurPrice":30.460,"GbpPrice":26.260,
    "RunType":"EP2","SystemLoad":2702.651},{"EffectiveTime":"01-Oct-2016 04:30:00","EurPrice":30.460,"GbpPrice":26.260,"RunType":"EP2",
      "SystemLoad":2694.620},{"EffectiveTime":"01-Oct-2016 05:00:00","EurPrice":30.510,"GbpPrice":26.300,"RunType":"EP2","SystemLoad":2718.430}]'''

dict_list = json.loads(text)
for d in dict_list:
    print(d)

结果:

{u'GbpPrice': 26.26, u'EffectiveTime': u'01-Oct-2016 04:00:00', u'EurPrice': 30.46, u'SystemLoad': 2702.651, u'RunType': u'EP2'}
{u'GbpPrice': 26.26, u'EffectiveTime': u'01-Oct-2016 04:30:00', u'EurPrice': 30.46, u'SystemLoad': 2694.62, u'RunType': u'EP2'}
{u'GbpPrice': 26.3, u'EffectiveTime': u'01-Oct-2016 05:00:00', u'EurPrice': 30.51, u'SystemLoad': 2718.43, u'RunType': u'EP2'}

使用完整转储（包括调试头）可以获得相同的结果，如下所示：

import json

text='''{"Debug":"Key:01-Oct-2016 04:00:00_04-Dec-2016 23:45:00,Age:-1","ErrorMessage":null,"LastUpdated":"06-Dec-2016 15:14:14","Rows":

{"EffectiveTime":"01-Oct-2016 04:30:00","EurPrice":30.460,"GbpPrice":26.260,"RunType":"EP2","SystemLoad":2694.620},{"EffectiveTime":"01-Oct-2016 05:00:00","EurPrice":30.510,"GbpPrice":26.300,"RunType":"EP2","SystemLoad":2718.430}]}'''

main_dict = json.loads(text)
for d in main_dict["Rows"]:  # access "Rows" member
    print(d)

如何将其应用于所有行？如何将其应用于所有行？非常感谢！！非常感谢你！！
