PhD in Mathematics.

Self-taught Python since August 2022. And self-taught R since much longer.

Please, do not hesitate to comment on everything I write here on SO. I am always open to and accept constructive criticism, suggestions and better ways of doing things.

In case you downvote one answer of mine, please explain why, to let my learning to be improved. I do not really care about my StackOverflow reputation, since it is inconsequential, as I am very self-confident and have a good, exciting and permanent job -- my single goal is to learn and help others.

If my answers helped you, please ponder to buy me a coffee

Thanks!
