使用class计算python中条目列表的平均值

class AverageCalculator:
    def __init__(self, items):
        self.items = items
    
    def calculate_average(self):
        total = sum(self.items)
        length = len(self.items)
        average = total / length
        return average

# 示例用法
items = [1, 2, 3, 4, 5]
calculator = AverageCalculator(items)
average = calculator.calculate_average()
print("平均值为:", average)
