And it didn't. It seems something implemented in 3.10 according to the other commentary. I used this in C# and Java, but didn't tried in Python just thinking it hadn't it.

i liked this - this is how i done it. Although i think i may have been bias; been coding a few years in python and would not have consided looking into a switch function or similar. I've been brushing on C++ and CUDA over the past few weeks and made be try what i would consider doing in C++. Which also makes me wonder, how does this solution stack in terms of execution time and memory compared to others. Anyone done any profiling on it?

Nice kata! I think it's better using "T" instead of "10", so you can access the card value easily

This will not work for columns with multiple letters such as "AA1:AB2", watch my solutions (works for thi case)

it came with python 3.10

:sad

Seriously!?!?!?!?

most likely, there is an error in the compatibility of numpy and decimal. they give different answers. I'll try to come up with something, but for now I can only advise not to use numpy in solving this kata

Hello. No, it's a bug. I didn't think through that someone would use numpy. Thanks for the information, I will try to fix the problem in the near time

It's a little bit weird but OK

I think it's like cheating but OK
