对于一行程序，使用userandom。示例(list_to_be_shuffled, length_of_the_list)与示例:

import random
random.sample(list(range(10)), 10)

输出: [2,9,7,8,3,0,4,1,6,5]

import random
class a:
    foo = "bar"

a1 = a()
a2 = a()
b = [a1.foo,a2.foo]
random.shuffle(b)

你可以使用shuffle或者sample。它们都来自于随机模块。

import random
def shuffle(arr1):
    n=len(arr1)
    b=random.sample(arr1,n)
    return b

OR

import random
def shuffle(arr1):
    random.shuffle(arr1)
    return arr1

对于一行程序，使用userandom。示例(list_to_be_shuffled, length_of_the_list)与示例:

import random
random.sample(list(range(10)), 10)

输出: [2,9,7,8,3,0,4,1,6,5]

对于numpy(科学和金融应用程序的流行库)，使用np.random.shuffle:

import numpy as np
b = np.arange(10)
np.random.shuffle(b)
print(b)

""" to shuffle random, set random= True """

def shuffle(x,random=False):
     shuffled = []
     ma = x
     if random == True:
         rando = [ma[i] for i in np.random.randint(0,len(ma),len(ma))]
         return rando
     if random == False:
          for i in range(len(ma)):
          ave = len(ma)//3
          if i < ave:
             shuffled.append(ma[i+ave])
          else:
             shuffled.append(ma[i-ave])    
     return shuffled
