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#L46 https://github.com/pallets/flask/blob/main/src/flask/cli.py#... https://github.com/pallets/flask/blob/main/src/flask/cli.py#L141 https://github.com/pallets/flask/blob/main/src/flask/cli.py#... https://github.com/pallets/flask/blob/main/src/flask/cli.py#L142 https://github.com/pallets/flask/blob/main/src/flask/cli.py#... https://github.com/pallets/flask/blob/main/src/flask/cli.py#L821 https://github.com/pallets/flask/blob/main/src/flask/cli.py#... https://github.com/pallets/flask/blob/main/src/flask/cli.py#L1016-L1019 https://github.com/pallets/flask/blob/main/src/flask/cli.py#... https://github.com/pallets/flask/blob/main/src/flask/cli.py#L1023-L1025 https://github.com/pallets/flask/blob/main/src/flask/cli.py#... https://github.com/pallets/flask/blob/main/src/flask/cli.py#L1027 https://github.com/pallets/flask/blob/main/src/flask/cli.py#... https://github.com/pallets/flask/blob/main/src/flask/cli.py#L1031 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!"
