一: dict <-> json

import json

dict = {
        "a": None,
        "b": False,
        "c": 123,
        "d": "string",
        "tuple": (123, "str"),
        "subject_list" : ["English", 123, "Math"],

data_json = json.dumps(dict)      # 数据转换 : dict - json
print(type(data_json), data_json)

data_dict = json.loads(data_json) # 数据转换 : json - dict

print(type(str_json), str_json)

data_dict = json.loads(str_json)
print(type(data_dict), data_dict)

二: dict <-> str

                "Math" : 100
        }
}
print(type(dict), dict, "\n")

dict_to_str = str(dict)  # 数据转换 : dict - str
print(type(dict_to_str), dict_to_str, "\n")

str_to_dict = eval(dict_to_str)  # 数据转换 : str - dict
print(type(str_to_dict), str_to_dict, "\n")

 

<class 'dict'> {'a': None, 'b': False, 'c': 123, 'd': 'string', 'tuple': (123, 'str'), 'subject_list': ['English', 123, 'Math'], 'dict': {'English': 88, 'Chinese': 92, 'Math': 100}} 

<class 'str'> {'a': None, 'b': False, 'c': 123, 'd': 'string', 'tuple': (123, 'str'), 'subject_list': ['English', 123, 'Math'], 'dict': {'English': 88, 'Chinese': 92, 'Math': 100}}

四: 传参json

# 传参数据格式 - 要求json
# 方法一
import requests

dict = {
        "a": None,
        "b": False,
        "c": 123,
        "d": "string",
        "tuple": (123, "str"),
        "subject_list" : ["English", 123, "Math"],
        "dict" : {
                "English" : 88,
                "Chinese" : 92,
                "Math" : 100
        }
}

url = "http://bin.org/post"
r = requests.post(url, json=dict) # 自动转换 : dict - json 


    
# 传参数据格式 - 要求json
# 方法二
import requests
import json

dict = {
        "a": None,
        "b": False,
