在python中，用基于另一个json的键交换json值。

import json

# 假设这是你的两个JSON对象
json1_str = '{"key1": "value1", "key2": "value2"}'
json2_str = '{"key3": "value3", "key4": "value4"}'

# 将JSON字符串转换为Python字典
json1_dict = json.loads(json1_str)
json2_dict = json.loads(json2_str)

# 假设我们想要交换key1和key3的值
# 首先检查键是否存在
if 'key1' in json1_dict and 'key3' in json2_dict:
    # 交换值
    json1_dict['key1'], json2_dict['key3'] = json2_dict['key3'], json1_dict['key1']

# 将字典转换回JSON字符串
json1_str_updated = json.dumps(json1_dict)
json2_str_updated = json.dumps(json2_dict)

print("Updated JSON1:", json1_str_updated)
print("Updated JSON2:", json2_str_updated)

Updated JSON1: {"key1": "value3", "key2": "value2"}
Updated JSON2: {"key3": "value1", "key4": "value4"}
