Efficiently Identify Rows with Zero Values in Pandas DataFrames Using GroupBy and Aggregate Functions
Based on your explanation, the approach you provided to solve this problem is correct and efficient. The use of the transform function to apply the any function along the columns, which returns a boolean mask where True indicates at least one non-zero value exists in that row, is a good solution. Here’s why: When you call df.groupby('FirstName')[['Value1','Value2', 'Value3']].transform('any').any(axis=1), it first groups the DataFrame by the values in the ‘FirstName’ column and then applies the ‘any’ function to each row.
