Python练习笔记——采用生成器函数实现两数之间的偶数计算

题目：编写一个生成器函数myeven(start, end)，采用迭代器逐次实现[start, end)范围内的偶数计算2 4 6 8. ...

def myeven(start, end):
    while start < end:
        if start % 2 == 0:
            yield start
        start += 1
    return "生成偶数结束"
 
gen = myeven(1, 10000)
 
#生成迭代器
it = iter(gen)
v = next(it)
print(v)
v = next(it)
print(v)
v = next(it)
print(v)
v = next(it)
print(v)

运行结果
