如何减少不同变量名的重复代码(python)

def process_data(data):
    # 假设这里是重复的处理逻辑
    result = data * 2
    return result

# 使用函数处理不同的变量
var1 = process_data(5)
var2 = process_data(10)

data_list = [5, 10, 15]
results = []

for data in data_list:
    result = data * 2
    results.append(result)

# 使用列表
data_list = [5, 10, 15]
results = [x * 2 for x in data_list]

# 使用字典
data_dict = {'var1': 5, 'var2': 10, 'var3': 15}
results_dict = {key: value * 2 for key, value in data_dict.items()}

class DataProcessor:
    def __init__(self, data):
        self.data = data
    
    def process(self):
        return self.data * 2

# 创建对象并处理数据
processors = [DataProcessor(5), DataProcessor(10), DataProcessor(15)]
results = [processor.process() for processor in processors]

def double_decorator(func):
    def wrapper(*args, **kwargs):
        result = func(*args, **kwargs)
        return result * 2
    return wrapper

@double_decorator
def get_data(value):
    return value

# 使用装饰器处理数据
var1 = get_data(5)
var2 = get_data(10)
