How would you perform a two-way pivot table in Python using Pandas?

Pandas can be used to perform a two-way pivot table in Python using the pivot_table() method. The pivot_table() method takes a data frame as an argument and can be used to reshape the data frame into a two-way pivot table. It takes several parameters, including values, index, columns, aggfunc, and fill_value. For example, if we want to calculate the total sales for each customer for each product, we can use the following statement: 

pd.pivot_table(data, values="sales", columns="product", index="customer", aggfunc="sum", fill_value=0)<|im_end|>
