PivotTable is a powerful tool for classifying and summarizing data and statistical analysis. By setting new row label index and column label columns, specifying the numerical values to be statistically analyzed, specifying the statistical aggregation function aggfunc, etc., PivotTable can be used to analyze the original data table from multiple perspectives and reshape it in different ways, so it is called PivotTable.

In the Pandas of Python, you can use the groupby method or pivot_table function to complete the classification and summary to achieve the function of PivotTable. Groupby is first grouped, and then the aggregate function is selected to generate a PivotTable. Pivot_table generates PivotTable directly by setting parameters such as index,columns,values,aggfunc.
