如何将变量重置为默认蓝图？

def process_data():
    data = [1, 2, 3]  # 默认蓝图
    try:
        # 处理数据的逻辑
        data.append(4)
    except Exception as e:
        print(f"Error: {e}")
        data = [1, 2, 3]  # 重置为默认蓝图
    return data

DEFAULT_DATA = [1, 2, 3]

data = DEFAULT_DATA  # 初始化为默认蓝图

def reset_data():
    global data
    data = DEFAULT_DATA  # 重置为默认蓝图

# 使用示例
try:
    data.append(4)
except Exception as e:
    print(f"Error: {e}")
    reset_data()

class DataProcessor:
    def __init__(self):
        self.data = [1, 2, 3]  # 默认蓝图

    def reset(self):
        self.data = [1, 2, 3]  # 重置为默认蓝图

processor = DataProcessor()
try:
    processor.data.append(4)
except Exception as e:
    print(f"Error: {e}")
    processor.reset()
