Python迭代器的反复使用

Posted 2020-12-21 Mr.Higgerw

代码：

def data_iter(n):
    for i in range(n):
        yield (i*i,i*i*i)

for epoch in range(3):
    print("++++++In for Loop++++++")
    for a,b in data_iter(5):
        print("a = ", a, end=" ")
        print("b = ", b)

执行结果：

即使内循环结束，每次外循环都会从头开始调用迭代器
