python random的里面的方法其实是Random实例化的对象。 里面几个常用的几个方importrandom print(random.randint(1,10))# 产生 1 到 10 的一个整数型随机数print(random.random())# 产生 0 到 1 之间的随机浮点数print(random.uniform(1.1,5.4))# 产生 1.1 到 5.4 之间的随机浮点数,区间可以不是整数print(...

某Python程序如下: from random import randint a=[1,8,3,6,7,2,9,0,5,1,3] s=[-1]*100;top=-1 i=0 x=randint(5,8) while i<x; while top!=-1 and a[i] < s[top]: top-=1 top+=1;s[top]=a[i] i+=1 while top!=-1:...
本题考查的是python循环。自定义函数fun(a,x)的功能是:返回列表a中能被x整除的元素(前后顺序与原列表a相同),randint(3,5)生成的是3到5的随机整数,即t的取值为3或4或5。 当t=3时,a=[3,5,16,9,8,5]能3整除的有3、9,故返回a值为:[3,9]; 当t=4时,a=[3,5,16,9,8,5]能4整除的有16、...
