Pretty Powerful Pandas - Merging DataFrames: SQL Meets Python

In this episode of Pretty Powerful Pandas, we dive into one of the most essential skills in real-world data analysis: joining tables. Using the Global Superstore dataset, I walk through how to: Load multiple sheets from Excel Merge two real tables (Orders + Returns) using .merge() Handle column conflicts (like Region_x and Region_y) Fill in missing values And most importantly — use that merged data to uncover insights like total profit lost from returns and most frequently returned products. If you’re used to SQL joins or Excel VLOOKUPs, this is how you bring that logic into your Python workflow — all in one tidy script. --------------------------------------------------------------------- We are Datacove, your data and analytics partner. https://www.datacove.co.uk Please hit the 'subscribe' button to make sure you never miss our free learning material here.
