如何用JSON file...not中的值替换文本文件中的特定键

import json

def replace_text_with_json(json_file, text_file):
    # 读取JSON文件
    with open(json_file, 'r') as f:
        json_data = json.load(f)

    # 读取文本文件
    with open(text_file, 'r') as f:
        text_content = f.read()

    # 替换键值
    for key, value in json_data.items():
        text_content = text_content.replace(key, str(value))

    # 更新文本文件
    with open(text_file, 'w') as f:
        f.write(text_content)

# 示例用法
replace_text_with_json('data.json', 'text.txt')
