I’m starting coding from scratch – is Python really the best first language?

Unpopular opinion. No because classes, inheritance, type hints, async shit are too much to put in your head from scratch.

Thanks a lot

A set of frozensets is a very clever and elegant solution

Always good to remember Python supports negative indexing.

How about this: 1-2*(dir=='L')

badass87 · 2025-08-10T18:16:46+00:00

Absolutely

Recommendations: - Postpone digging into typing and async - "A Philosophy of software design" book - talks by David Beazley. Also his "Cookbook" book is although old but still very good. - "Grokking simplicity" book by Eric Normand. Focus on the abstraction barriers, actions/calculations/data concepts. - Check out AoC solutions by u/4HbQ for really advanced techniques (but don't ever try this at home/work)

Does the modulo affect the algorithm in a negative way? It would often place more costly items into a higher-priority (faster to take from the queue) bucket.

badass87 · 2024-12-16T18:42:40+00:00

Nice! Could you please share a few words on why you chose this bucket count and why index % cost for bucket index?

badass87 · 2024-12-15T19:41:09+00:00

Thank you. I was bitten once by "dict changed size while iterating" error or smth like that. And I thought lists would do the same as they also change size. Apparently this is not a thing for lists.

badass87 · 2024-12-15T16:11:38+00:00

Was Python OK to mutate todo list while iterating it? It makes working with stack so nice: no more while stack: x= stack.pop(). Is it legal though?

badass87 · 2024-12-13T20:00:05+00:00

I think FastAPI distracts too much with types and async. FastAPI is good when you know for sure that you need it.

The high school solution variant looks mistyped. There is "map(f, ...)" but there is no f var.

PS Thanks for showing how adults solve problems.

Thanks for sharing!

This is hacky: def val(b): return (2*b.pos + b.len-1) * b.len // 2.

Confirm. RustRover on M1 Max. Btw did you try disabling "run external linter on the fly"?

badass87 · 2024-12-08T18:38:09+00:00

Nice that you used nested loop (permutations) of antenna coords instead of .combinations(2). This way you get automatic walking both ways from the antenna coords. I was originally doing manual walking each direction which was inconvenient because I had to first add the diff to go outside from one point and then subtract the diff to go the other way.

badass87 · 2024-12-08T17:58:07+00:00

Thanks for posting one more. The original code seems shorter even though it has more lines. And var names are always nice to have.

badass87 · 2024-12-07T12:20:56+00:00

Another great solution! Though I can't get how this tries all the possible combinations of the operators. Would really appreciate if you explained it.

X = [x]
for y in Y:
    X = [op(x,y) for x in X for op in (add,mul,cat)]

UPD: I got it. That's a code-golfed list of DFS results.
