014 乱序列表元素有哪些方式

1 . 编写一个函数（不要使用python模块的函数），打乱列表元素的顺序

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

import random   a = [1,2,3,4,5,6,7,8,9, 0] def random_list1(a):     for i in range(0, 100):         index1 = random.randint(0, len(a) - 1)         index2 = random.randint(0, len(a) - 1)         a[index1], a[index2] = a[index2], a[index1]     return a   b = random_list1(a) print(b)   def random_list2(a):     a_copy = a.copy()     result = []     count = len(a)     for i in range(0, count):         index = random.randint(0, len(a_copy) - 1)         result.append(a_copy[index])         del a_copy[index]     return  result   a = [1,2,3,4,5,6,7,8,9,0] b = random_list2(a) print(b)

　　

 

2. 如何对列表元素进行随机排列

1 2 3

a = [1,2,3,4,5,6,7,8,9,0] random.shuffle(a) print(a)
