是可以打乱多组数据的，不局限与x，y。
python">import numpy as np
import random
from sklearn.utils import shuffle
a = np.array([1,2,3,4,5])
b = np.array([0.1,0.2,0.3,0.4,0.5])
c = np.array([-1,-2,-3,-4,-5])
a,b,c = shuffle(a,b,c)
print(a)
print(b)
print(c)
# output:
# [1 4 2 5 3]
# [0.1 0.4 0.2 0.5 0.3]
# [-1 -4 -2 -5 -3]
