What is the Difference Between axis=0 and axis=1 When Working with Pandas Dataframes?

This article clarifies the often confusing concept of axis parameter in Pandas functions like apply() and mean(). Using a car sales dataset, it demonstrates axis=0 (apply function to each column) and axis=1 (apply function to each row) through practical scenarios. Lucy's question about average per color uses axis=0, while Zack's question about average per row uses axis=1. Includes code examples and explanations for beginners.
