Python Question

I have a 2D array

`x`

`y`

`import numpy as np`

x = np.array([[1, 2], [4, 5], [3, 3]], np.int32)

y = np.array([1, 2, 3, 4, 5, 6])

x[:,:] = y # i would like x to be [[1, 2], [3, 4], [5, 6]]

ValueError: could not broadcast input array from shape (6) into shape (3,2)

How to do this ?

Answer

You have to convert the `y`

to an array with a shape like `x`

:

```
>>> x = y.reshape(x.shape)
>>> x
array([[1, 2],
[3, 4],
[5, 6]])
```

But note that the `y`

should be reshape with `x`

's shape.
