In my last post, I mentioned working with groupby technique  in Pandas library. I will talk about pivot table in this post. A pivot table is a tool that summarizes the spread data set. This tool combines the data set into a rectangular table using one or more key columns.

Sometimes the difference between pivot tables and groupby is confusing. Pivot tables can be thought of as the multidimensional of groupby grouping.

In summary, I will explain the following topics in this post.

• What is the groupby method in short?
• What is the difference between pivot_table and groupby method?
• What are the functions that can be used with -pivot_table?
• What are multi-level pivot tables?
• What are crosstab tables?
• How to make a sample application with real data set?
