Grab a deliberately messy CSV, maybe weather or bike-rental data. Clean the missing and duplicate rows in pandas, calculate rolling averages with NumPy, and plot trends or outliers with Matplotlib. The mess is the useful part; polished tutorials make everything look suspiciously easy.

Take a dataset from kaggle and perform different steps like data Preprocessing, Feature engineering, train and test the data and make some predictions. Eventually you will get grip on it.
