python如何搜索字符串

想在一个string里面查找一些关键字及其后面的一些数据，应该怎么做？比如：

            "poiweight": [ ]
        }
    ]
}

这里随便举了个例子，我想要‘location’和后面的数字，但不要其他的字符（包括‘location’）应该怎么做？

Answer 1

Daripada format, ini kelihatan seperti json Anda boleh membaca rentetan ini menjadi pembolehubah, seperti

import json

with open('test.json','r') as f:
    vContact=json.load(f)
    for i in vContact['pois']:
        print(i['location'])

Dapatkan data yang anda mahu location, saya tidak tahu sama ada saya faham dengan betul
