Numpy Array examples error

[s0rta]

The code for the numpy array examples are being written as if the page was a jupyter notebook, but code written in a block is only allowed to see the code inside that block. I tried to fix it, but some of the code blocks seem to be serialized. New students will not understand this section because of all of the blocks past the first one throwing errors.

Also, the code block height is being set using 'data-height' which does not seem to do anything, as all of the blocks are being set to the min height of 150, which makes the code hard to read.
