如何迭代地创建一组JSON类型的字符串文字？

import json

# 创建空的JSON数组对象
json_array = []

# 迭代生成JSON字符串
for i in range(3):
    # 创建空的JSON对象
    json_obj = {}

    # 添加键值对
    json_obj['key1'] = 'value1'
    json_obj['key2'] = 'value2'

    # 将JSON对象转换为字符串
    json_str = json.dumps(json_obj)

    # 将JSON字符串添加到JSON数组对象
    json_array.append(json_str)

# 将JSON数组对象转换为字符串
result = json.dumps(json_array)

print(result)

["{\"key1\": \"value1\", \"key2\": \"value2\"}", "{\"key1\": \"value1\", \"key2\": \"value2\"}", "{\"key1\": \"value1\", \"key2\": \"value2\"}"]
