python中json模块

import json
string = '{"name":"xxx","age":18,"object":[{"数学":100,"语文":90,"英语":70}]}'
print(string)
print(type(string))
# 将json字符串转为python字典
data_dic = json.loads(string)
print(data_dic)
print(type(data_dic))
# 将python字典转为JSON字符串
res1 = json.dumps(data_dic)
print(res1)
print(type(res1))

res2 = json.dumps(data_dic, ensure_ascii=False)
print(res2)
print(type(res2))

res3 = json.dumps(data_dic, separators=(",", ":"))
print(res3)
print(type(res3))

res4 = json.dumps(data_dic, separators=(",", ":"), ensure_ascii=False)
print(res4)
print(type(res4))
# f-string
print("\u8bed\u6587")
