OM.

Wow you've saved so many energy with this short names!

veky on Aug. 30, 2021, 6:50 p.m.
I'm not sure whether you're ironic, but the biggest problem is that those names don't have any nontrivial semantics. "list" and "element" (or "border"(?)) would do just fine, but when the name is this void of meaning, I refuse to spend many letters on it. :-)

<pre class='brush: python'>L[L. </pre> for me this place looks especially aweful, hard to read. Capitalised variables? But when you named it L you meant list, didn't you? Please, be more indulgent for people who have to read your code ;-)

This is a perfect example of the impossibility of pleasing everyone. If I named it `list`, someone would object to using a builtin name for my objects. (People actually did that.) If I named it `l`, someone would object to using a letter which is too similar to the digit `1` in certain fonts. (People actually did that.) If I named it `L`, someone would object to using "capitalised variables" (whatever that means). (You actually did that.) I guess the only thing I haven't tried is to name it `foo`. But I guess someone would object to that too. :-D <hr /> And `L[L.` is not a subexpression of what I wrote. It's as if you object to "WC" in "I have a new car.".

Well, now you have fully convinced me that you chose the names of variables of one letter not because you are too lazy to hit the keyboard )))

veky on Sept. 1, 2021, 8:22 p.m.
Absolutely. Wait until you see one of my oneliners explained in 4kb of text. ;-P

remdch on Sept. 1, 2021, 8:24 p.m.
but anyway you'd better put new line after colons )

veky on Sept. 1, 2021, 8:25 p.m.
Why? ;-) [Please use at least three newlines when replying.;]]

I'm blown away by the simplicity of your solution to this problem. I felt so proud of my multi-step approach to resolving this challenge, only to then be shown the forest for the trees lmao.

Yes, the task is in fact much simpler than it seems at the first glance, but to see that you have to think a bit. 😛

I like a solutions using 'try-except' statements. It is good.

veky on Sept. 9, 2021, 7:42 a.m.
It is the {right tool for the job}™. Note the "edge cases" in the task description. (Plural is nonsense, case (2) is just a particularization of case (1).)

Great!

This is a great solution which I do not know why I haven't thought of it before!

👍 Pythonic. "Ask forgiveness, not permission"

This is fine pythonic solution.

beautiful, what else can I add?)

List but not the least
