How can I reshape a NumPy array in Python?
You can use the reshape()
method in NumPy to change the shape of an array. For example, array.reshape(new_shape)
.
Can you show me an example of reshaping a 1D array to a 2D array?
Sure! If you have a 1D array like np.array([1, 2, 3, 4, 5, 6])
, you can reshape it to 2D with array.reshape(2, 3)
.
What happens if the new shape is not compatible with the original array size?
If the new shape is not compatible, NumPy will raise a ValueError
. The total number of elements must remain the same.
Can I reshape an array in place?
No, the reshape()
method returns a new array. If you want to keep the reshaped array, you need to assign it to a variable.
