Learn how to use python pandas agg () function to perform aggregation operations like sum, mean, and count on dataframes. In this tutorial we will discuss about how to use the dataframe.agg () method to perform various aggregation techniques, including how to apply multiple aggregation functions, customize aggregations for specific columns, and work with both rows and columns. The agg() method allows you to apply a function or a list of function names to be executed along one of the axis of the dataframe, default 0, which is the index (row) axis.
