将 ndarray 数据移动到另一个

Question

I want to move the np.array with 3 rows and 2 columns into a.

import numpy as np
a = np.zeros((3,2))
a[:,1] = np.array([[3],[3],[3]])

but some errors there.

Exception has occurred: ValueError
 could not broadcast input array from shape (3,1) into shape (3,)

Would you tell me how to move it?

Answer 1

import numpy as np
a = np.zeros((3,2))
a[:,1] = np.array([3,3,3])
