Issue
In
03_Grouping/Alcohol_Consumption/Exercise_with_solutions.ipynb, Step 6 (drinks.groupby('continent').mean()) raises aTypeErrorin modern pandas versions (e.g., 2.x) due to attempting to compute the mean of the non-numericcountrycolumn.Fix
Updated the code to
drinks.groupby('continent').mean(numeric_only=True)to exclude non-numeric columns, ensuring compatibility with pandas 2.x.Impact
This fixes the error and aligns the solution with current pandas behavior, improving the exercise for learners.
