但是和生成器一样,生成器表达式也是返回生成器generator对象,一次只返回一个值。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>sum(i*iforiinrange(10))# sumofsquares285>>>xvec=[10,20,30]>>>yvec=[7,5,3]>>>sum(x*yforx,yinzip(xvec,yvec))# dot product260>>>from mathimportp...
生成器(Generator)是一个含有yield表达式的函数,如例所示。 上述代码中yield_gen()函数就是一个生成器,通过yield关键字来阻塞当前函数执行,并返回yield结果直到当前循环结束,例运行结果如图所示。 Ø 协程 协程(coroutine)也是一种程序组件,执行过程与子例程类似,但协程更为灵活,在实践中的使用没有子例程广泛,协程...
def main_generator(): yield from sub_generator(1, 5) yield from sub_generator(6, 10) for value in main_generator(): print(value) 这段代码中,main_generator通过两次yield from调用了sub_generator,将子生成器产生的平方数“合并”到主生成器的输出中。 3.1.2 yield from与嵌套生成器 yield from尤其...

from .chart import * from .generator import * 正如你所看到的,我们正在使用相对导入将所有这些模块中的函数加载到主charter包的命名空间中。我们的 Charter 库开始成形了!现在让我们依次处理这两个模块。实现chart.py 模块由于我们在 Charter 库的实现中避免使用面向对象的编程技术,我们不能使用对象来存储有关图表...
Note: Using yield turns .parse() into a generator that yields its results rather than returning them. This allows the framework to handle multiple requests and responses concurrently. Scrapy is built on top of the Twisted framework, which is an event-driven networking engine that allows for ...
