sumif() function is used to perform sum operation by a group of items in the dataframe, It can be applied on single and multiple columns and we can also use this function with groupby function.sum() to Sum All Columns. Use DataFrame. sum() to get sum/total of a DataFrame for both rows and columns, to get the total sum of columns use axis=1 param. By default, this method takes axis=0 which means summing of rows.Since you have already mastered SUMIF and SUMIFS in pandas, to do COUNTIF(S), all we need is to replace the sum() operation with the count() operation. In fact, if we replace sum() in the above examples with: mean() – will give AVERAGEIF(S) max() – will give MAXIFS.
- Select cell G4 and click on it.
