MATLAB 命令 x=rand(10,1)生成 10 个随机数， 将它们从大到小排序， 使用 A: y=sort(x);z=y(10:1) B: [y,Ⅱ ]=sort(x);z=y(Ⅱ ) C: y=sort(x);z=y(10:-1:1) D: [y,Ⅱ ]=sort(x);z=x(Ⅱ )

编写程序，生成包含20个随机数的列表，然后将前10个元素升序排列，后10个元素降序排列，并输出结果。 import random[br][/br] x = [random.randint(0,100) for i in range(20)] print(x) 1 [br][/br] y.sort() x[0:10] = y 2 y.sort(reverse=True) x[10:20] = y print(x)
