pandas
A Python library for **tables of data** — load CSVs, filter rows, compute stats, and prep features for ML labs.
When to use
Exploring datasets before training, cleaning labels, or joining columns for a tiny model.
When not to
When you only need a short list in memory — plain Python lists may be enough for the smallest demos.
Example
import pandas as pd
df = pd.read_csv("scores.csv")
df["high"] = df["score"] >= 0.5
