To achieve this, we have to specify a list of group columns within the groupby function.Consider the Python syntax below:print(data.groupby(['group1', 'group2']).mean()) # Get mean by multiple groups # x1 x2 # group1 group2 # A a 4.5 12.0 # b 8.0 18.0 # B a 5.0 12.0 # ...

calculate takes very little additional time to process, the speed gain over 3 field calculations is much faster that the previous script. As a result, the more field calculations you can replace with a single pass of a da UpdateCursor, the more dramatically the speed of the script ...
