在嵌套的复杂JSON中搜索关键字

import json

def search_keyword(data, keyword):
    if isinstance(data, dict):
        for key, value in data.items():
            if key == keyword or search_keyword(value, keyword):
                return True
    elif isinstance(data, list):
        for item in data:
            if search_keyword(item, keyword):
                return True
    else:
        return keyword in str(data)
    return False

# 示例JSON数据
json_data = '''

    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "Anytown"
    },

data = json.loads(json_data)
keyword = "Python"

if search_keyword(data, keyword):
    print(f"Keyword '{keyword}' found in JSON data.")
else:
