你有JSON数据;使用json module来解析它。从那里开始，您可以访问operatingssystems列表并搜索给定名称：
import json
data = json.loads(body)
name_to_find = 'foobar'
uuid = next((d['uuid']
for d in data['operatingsystems']
if d['name'] == name_to_find), None)
演示：
>>> import json
>>> data = json.loads(body)
>>> name_to_find = 'OpsMgmt node'
>>> next((d['uuid']
... for d in data['operatingsystems']
... if d['name'] == name_to_find), None)
u'1d15250f-ec0b-42e9-9e61-4da92024e024'
