Thanks Liam for a great tutorial on working with dictionaries. I learned a lot of new things especially using ChainMap, the itertools and dict unpacking.

I am a data engineer so work with dictionaries a fair bit. Although I was familiar with a lot of the concepts, I still picked up a number of new things, like ChainMap! And a brilliant use case for popitem! Loved the presenting skills and the material was very valuable. Will look to see if I can apply some of the learnings to my job and in fun challenges :) Great work Liam!

Great presentation. Useful stuff that was new to me, also pointers to other areas to look into. I liked you delivering it ‘warts and all’. It is always helpful to see mistakes and their redemption. Many thanks.
