How do I use numpy's reshape function?
The reshape function in numpy allows you to change the shape of an array without changing its data. You can specify the new shape as a tuple.
Can you give me an example of how to reshape a 1D array into a 2D array?
Sure! If you have a 1D array like np.array([1, 2, 3, 4, 5, 6]), you can reshape it to a 2D array with 2 rows and 3 columns using 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 use reshape to flatten an array?
Yes! You can flatten an array by reshaping it to -1, like this: array.reshape(-1), which will create a 1D array.
