—b站 python数据分析(黑马程序员)

常用前两种
swapaxes为交换轴
import numpy as np
t1 = np.arange(24).reshape(4, 6)
print(t1)
[[ 0 1 2 3 4 5]
[ 6 7 8 9 10 11]
[12 13 14 15 16 17]
[18 19 20 21 22 23]]
print(t1.transpose())
print(t1.T)
print(t1.swapaxes(1, 0))
[[ 0 6 12 18]
[ 1 7 13 19]
[ 2 8 14 20]
[ 3 9 15 21]
[ 4 10 16 22]
[ 5 11 17 23]]
