numpy常见代码段

同序shuffle

import numpy as np
 
a = np.arange(0,10,1)
b = np.arange(10,20,1)
print(a,b)
#result:[0 1 2 3 4 5 6 7 8 9] [10 11 12 13 14 15 16 17 18 19]
state = np.random.get_state()
np.random.shuffle(a)
print(a)
#result:[6 4 5 3 7 2 0 1 8 9]
np.random.set_state(state)
np.random.shuffle(b)
print(b)
#result:[16 14 15 13 17 12 10 11 18 19]
