如何使用多个组件过滤数据

class FilterComponent:
    def filter(self, data):
        raise NotImplementedError("Each filter component must implement this method.")

class EvenNumberFilter(FilterComponent):
    def filter(self, data):
        return [x for x in data if x % 2 == 0]

class PositiveNumberFilter(FilterComponent):
    def filter(self, data):
        return [x for x in data if x > 0]

class DataPipeline:
    def __init__(self, filters):
        self.filters = filters

    def process(self, data):
        for filter_component in self.filters:
            data = filter_component.filter(data)
        return data

# 使用示例
data = [1, -2, 3, -4, 5, 6]
filters = [EvenNumberFilter(), PositiveNumberFilter()]
pipeline = DataPipeline(filters)
filtered_data = pipeline.process(data)
print(filtered_data)  # 输出: [6]
