python3,斐波那契数列小代码,展示生成器作用

下面的小代码是应用斐波那契数列小代码,展示生成器作用

def fib(n):
    before,after = 0,1
    for i in range(n):
        yield before
        before,after = after,before + after
        

g = fib(10)
print(g)
for i in range(10):
    print(next(g))

运行结果如下:

<generator object fib at 0x7f923958bf10>
0
1
1
2
3
5
8
13
21
