the task above is not 15 lines of python with a real world dataset.
the tutorials you reference? yes, 15 lines of python when you're starting with the titanic.csv. But a real world dataset normally takes hours or days of cleaning before it's ready to run any statistical analysis on.
Data cleaning is hard. That is not what OP said they had Claude do. They just said Claude normalized it. Normalizing data does not take days unless you are learning to do both statistics and programming for the first time ever
