python中将字符串拼接成json

可以使用Python中的json.dumps()函数将Python字符串转换为JSON格式的字符串，然后将两个JSON格式的字符串进行拼接。例如：

import json

data1 = {"name": "Tom", "age": 18}
data2 = {"country": "China", "city": "Beijing"}

json_str1 = json.dumps(data1)
json_str2 = json.dumps(data2)

json_str = json_str1[:-1] + "," + json_str2[1:]

print(json_str)

输出结果为：

{"name": "Tom", "age": 18,"country": "China", "city": "Beijing"}
