在Python中遍历嵌套的JSON

import json

def traverse_json(json_obj, path=''):
    if isinstance(json_obj, dict):
        for key in json_obj:
            new_path = f"{path}.{key}" if path else key
            traverse_json(json_obj[key], new_path)
    elif isinstance(json_obj, list):
        for i, item in enumerate(json_obj):
            new_path = f"{path}[{i}]"
            traverse_json(item, new_path)
    else:
        print(f"{path}: {json_obj}")

# 示例JSON数据
json_data = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "Anytown",
        "zipcode": "12345"
    },
    "contacts": [
        {"type": "email", "value": "john@example.com"},
        {"type": "phone", "value": "555-1234"}
    ]
}

# 将JSON字符串转换为Python对象
data = json.loads(json.dumps(json_data))

# 遍历JSON数据
traverse_json(data)

import sys
sys.setrecursionlimit(1500)  # 设置新的递归深度限制

def traverse_json(json_obj, path='', visited=None):
    if visited is None:
        visited = set()
    if id(json_obj) in visited:
        return
    visited.add(id(json_obj))
    # ... 剩余代码不变 ...
