将多个字典附加到一个列表中并转储到json中

import json

# 创建一个空列表，用于存储字典数据
data_list = []

# 创建字典数据并附加到列表中
dict1 = {"name": "John", "age": 25, "city": "New York"}
data_list.append(dict1)

dict2 = {"name": "Emma", "age": 30, "city": "London"}
data_list.append(dict2)

dict3 = {"name": "Tom", "age": 35, "city": "Paris"}
data_list.append(dict3)

# 将列表转储为 JSON 格式的字符串
json_data = json.dumps(data_list)

print(json_data)

[{"name": "John", "age": 25, "city": "New York"}, {"name": "Emma", "age": 30, "city": "London"}, {"name": "Tom", "age": 35, "city": "Paris"}]
