int 类型无法调用

#请编写代码，测试一下到底是创建列表的速度快，还是创建元组的速度快？为了得到更精准的数据，请重复测试100次，并分别计算出平均速度。
import timeit
   
t_speed = timeit.repeat('t = (1, 2, 3, 4, 5)', repeat=100)
l_speed = timeit.repeat('l = ', repeat=100)

t_average = sum(t_speed) / len(t_speed)
l_average = sum(l_speed) / len(l_speed)
   
print("创建元组的平均速度是：", t_average)
print("创建列表的平均速度是：", l_average)

没啥毛病啊

>>> import timeit
>>> t_speed = timeit.repeat('t = (1, 2, 3, 4, 5)', repeat=100)
>>> type(t_speed)
<class 'list'>
>>> sum(t_speed)/len(t_speed)
0.01386857300021802
>>> l_speed = timeit.repeat('l = ', repeat=100)
>>> type(l_speed)
<class 'list'>
>>> sum(l_speed)/len(l_speed)
0.05656204100028844
>>>

你那中间红色的是啥玩意

你这贴的都是啥啊
报错代码是count你贴的代码是 len

麻烦认真一些好吗

看了一下应该是sum函数的问题
我在jupyternotebook中报错了
