62列表和元组访问速度对比

 

 

import time
import random
# python 列表 和元组通过千万级别的数据访问，对比耗时时间，元组访问速度不一定比列表快，还是列表略快过元组。
def ListTime():
    print('正在计算访问列表元素耗时时间')
    l = [i for i in range(10000000)]
    t1 = time.time()
    for _ in range(10000000):
        l[random.randint(0, 9999999)]
    t2 = time.time()
    h = t2-t1
    print(f"列表元素访问耗时:{h}s")
