Question

View Onto A NumPy Array
I have a 2D numpy array. Is there a way to create a view onto it that would include the first k rows and all columns?

Answer 1

It;s really easy, just specify the index value, for example:
x-> NumPy Array, K-> Rows that you want.
x[:k, :]

Answer 2

 just index it as you normally would. E.g. y = x[:k, :] This will return a view into the original array. No data will be copied, and any updates made to y will be reflected in x and vice versa.
