This lecture introduces the two fundamental pandas data structures—Series and DataFrame—and explains why their distinction matters in practice. We also introduce the idea of “tidy data” as a guiding principle for organizing tabular datasets so they are easier to analyze, visualize, and model.
Rather than treating pandas as a collection of commands, this module emphasizes structure: how data are represented, how columns and indices behave, and why many downstream operations become simpler (or harder) depending on how your data are laid out. Getting this right early prevents confusion and unnecessary complexity later.
