Creating a Dictionary from a List and DataFrame ============================================= In this article, we will explore how to create a dictionary from a list and a pandas DataFrame. The list contains tuples of values, and the DataFrame has multiple columns. We’ll use the set_index, reindex, and Series.to_dict functions to achieve this. Introduction Python’s pandas library provides efficient data structures and operations for working with structured data. When dealing with large datasets, it’s often necessary to manipulate data in different ways than with simple Python lists or dictionaries.

The problem here is that you are using a LEFT JOIN and then applying a SUM function to each column. This causes the SUM function to be applied multiple times for each row in the joined table, resulting in tripled data. To fix this, you can use windowed functions (analytic functions) instead of regular SUM functions. Windowed functions allow you to perform calculations over a set of rows that are related to the current row, without having to group by all columns.
