废话不多说了，直接上代码吧！
import numpy as np array = np.array([0, 0]) for i in range(10): array = np.vstack((array, [i+1, i+1])) print(array) # [[ 0 0] # [ 1 1] # [ 2 2] # [ 3 3] # [ 4 4] # [ 5 5] # [ 6 6] # [ 7 7] # [ 8 8] # [ 9 9] # [10 10]] rand_arr = np.arange(array.shape[0]) np.random.shuffle(rand_arr) print(array[rand_arr[0:5]]) # [[9 9] # [4 4] # [1 1] # [5 5] # [8 8]] np.random.shuffle(rand_arr) print(array[rand_arr[0:5]]) # [[10 10] # [ 3 3] # [ 4 4] # [ 8 8] # [ 5 5]]
