Really good use of a dictionary

Could someone explain to me how the line below works for the description?

if 2 < len(cells & get_neighbours(x, y)) < 4 + ((x, y) in cells)

from my understanding the above would match on 3 for a dead cell and 3 or 4 for a living cell but the description for the challenge dictates 3 for a dead cell and 2 or 3 for a living cell (not 3 or 4), would really appreciate if someone could help me figure out what I'm missing?

Wholy cow! My first attempt seems like the clumsiest one compared to this solution. Still a long way to go but loving the chance to understand better practices.

Yes.

Chapeau!

I feel so dumb rn because I used min(), max() and imported statistics to do statistics.median([]). I guess I still have much to learn. Only less than a week into all this.

Slick

Brilliant soulutin!

lol

ahahha I used the cosine rule but I could have done this. It always makes me chuckle when I overcomplicate a problem

Two important things I learned from this solution:

• sorted can take a set and make it a list
• using a generator expression insisde the any function is a nice thing to have in mind

Great

Awesome!am learn alot.Thanks codewars.
