numpy transpose()测试例子

x = np.array([[0, 1, 2, 3], ['a', 'b', 'c', 'd']])
print(x)
y = x.transpose()
print(y)
z = x.transpose(1,0)
print(z)
print(x.shape)
print(z.shape)

输出：

[['0' '1' '2' '3']
 ['a' 'b' 'c' 'd']]
[['0' 'a']
 ['1' 'b']
 ['2' 'c']
 ['3' 'd']]
[['0' 'a']
 ['1' 'b']
 ['2' 'c']
 ['3' 'd']]
