在主函数中,我们首先通过generate_data()生成了一个数据的生成器data_generator,然后使用for循环逐个处理数据,并打印结果。 通过使用生成器,我们可以逐个生成数据并逐个进行处理,而不需要一次性加载和处理全部数据。这样可以节省内存空间,并且保证不丢失任何数据。 类图 下面是本方案的类图,使用mermaid语法中的classDiagram...

<generator object func at 0x0000000002908630> >>> func 就是一个生成器函数,调用该函数时返回对象就是生成器 g ,这个生成器对象的行为和迭代器是非常相似的,可以用在 for 循环等场景中。注意 yield 对应的值在函数被调用时不会立刻返回,而是调用next方法时(本质上 for 循环也是调用 next 方法)才返回 ...
