            Pandas pivot_table: filter on aggregate function
            Asked 2021-Jun-07 at 18:15

            I am trying to pass a criteria to the aggregate function to pandas pivot_table and I am not able to figure out how to pass the criteria to the aggfunc. I have a data table which is converted to pandas df.

            The input table data:

            col1 col2 col3 col4 col5 col6 col7 1 test1 t1 Dummy1 result1 10 102.2 2 test1 t1 Dummy2 result2 20 101.2 3 test1 t1 Dummy3 result3 30 102.3 4 test1 t1 Dummy4 result4 40 101.4 5 test2 t1 Dummy1 result1 10 100 6 test2 t1 Dummy2 result2 20 103 7 test2 t1 Dummy3 result3 30 104 8 test2 t1 Dummy4 result4 40 105 9 test3 t1 Dummy1 result1 10 102 10 test3 t1 Dummy2 result2 20 87 11 test3 t1 Dummy3 result3 30 107 12 test3 t1 Dummy5 result4 50 110.2 13 test4 t1 Dummy2 result2 20 120 14 test5 t1 Dummy6 result1 100 88 15 test1 t1 Dummy1 result2 10 106.2 16 test1 t1 Dummy1 result6 10 101.1

            I want to get the maximum on col7 data, but only when the maximum is greater than 100. If any of the col7 data is greater than the user defined criteria, then all the other columns data needs to be populated irrespective if the data met the criteria or not.

            You can't compare the word 'max' to 100 via >= (aggfunc = 'max' >= 100):

            I recommend not setting the fill value to a string, masking the DataFrame, to get rid of undesired rows, then replace with empty string via fillna:

            You were almost there; after pivot, we just need to rename the axis using rename_axis and drop columns and index using drop which are not required.
