Creating 2D and 3D multidimensional arrays with NumPy

We can create ndarrays using the np.array function. We need to use nested lists to introduce the extra dimensions. As you can see when running this example, the output (when using print) can become a bit hard to read. This gets worse when even more dimensions are involved.

Array creation using lists is doable up to 2D arrays; beyond that, list nesting quickly becomes cumbersome and unreadable. In the upcoming sections, we will see how we can address high-dimensional array creation using more straightforward ways.

IFRAME

If you want to embed the crumb in an iframe, use the following code:

oEmbed (WordPress)

We support oEmbed, but most sites use allowlisting. On WordPress, oEmbed is supported out of the box, but see the note below.

If you plan to use crumb.sh heavily on Wordpress, you can use the following PHP code to allowlist our site and unlock all the functionalities of our crumbs:
wp_oembed_add_provider( 'https://crumb.sh/*', 'https://crumb.sh/oembed/' );

Embed.ly

Embed.ly is a service that allows you to embed content from other sites. We will request to be added to the list of trusted sites once we're out of beta.
