Name 'read_url' is not defined about textbook

So if you take a look at the ipynb file for the chapter here, you'll see it's a custom defined function in the header cell that we've hidden for the purposes of readability of the textbook. Ping back on this issue if you have any issues on using this :)

This is great - thank you for the quick response. It's possible I may have missed a mention of the expressions being in the ipynb files, so if so apologies.

That has worked and I understand now where to find the expressions on GitHub when I need them. Thank you again. I will close this issue for now, but if I have another more questions I will reply without re-opening.
