Ruby 3.2.0 Is from Another Dimension

I think this is purely a personal preference but I also think there is a bias towards list comprehensions being more difficult to mentally parse.

I do a lot of contract work and chatted with a ton of folks ranging from beginners to veterans. A lot of them (well more than half) avoid list compressions, especially when working with teams because it's such a mixed bag of either being able to instantly understand them or it requires more effort. Personally I don't use them in my code (for both reasons).

Both Ruby solutions are much more clear to me even though I have no functional programming background. I have no preference towards functional styles either, I would say it's the opposite. I struggled with Elixir long enough that I stopped using it.

I disagree about list comprehensions, as do more than half the people I’ve asked over the years.

I don’t use either, and also have an admittedly irrational dislike for Python. That said, the Python variant is more readable imo as well.

And yet, in the production Python codebases I've worked with, list comprehensions are rarely seen. Usually it's typical loop iterations. I wonder why that is?...

This says much more about you and the developers and codebases you work with than anything to do with Python list comprehensions.

Coming from a point of zero knowledge of the codebase, I picked Flask. I picked the cli.py module in Flask. And what do I find?

https://github.com/pallets/flask/blob/main/src/flask/cli.py#...

The keyword "for" occurs twice as often in comprehensions and generator expressions as it does in "typical loop iterations!"
