用python将数据追加到JSON文件？

import json

# 假设我们有一个JSON文件 'data.json'，内容如下：
# [
#     {"name": "Alice", "age": 30},
#     {"name": "Bob", "age": 25}
# ]

# 读取现有JSON文件
with open('data.json', 'r') as file:
    data = json.load(file)

# 追加新数据
new_data = {"name": "Charlie", "age": 35}
data.append(new_data)

# 将更新后的数据写回JSON文件
with open('data.json', 'w') as file:
    json.dump(data, file, indent=4)

try:
    with open('data.json', 'r') as file:
        data = json.load(file)
except json.JSONDecodeError:
    print("文件内容为空或格式不正确")
    data = []

try:
    with open('data.json', 'w') as file:
        json.dump(data, file, indent=4)
except PermissionError:
    print("文件被占用或没有写权限")
