Python:如何在获取的json数据中删除不必要的字符

import json

# 假设获取的JSON数据
json_data = '{"name": "John", "age": 30, "city": "New York"}'

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

# 删除不必要的字符
if isinstance(data, dict):
    for key, value in data.items():
        if isinstance(value, str):
            data[key] = value.strip()
        elif isinstance(value, list):
            data[key] = [item.strip() if isinstance(item, str) else item for item in value]
        elif isinstance(value, dict):
            for inner_key, inner_value in value.items():
                if isinstance(inner_value, str):
                    value[inner_key] = inner_value.strip()

# 将处理后的数据转换回JSON字符串
processed_json_data = json.dumps(data)

print(processed_json_data)
