- Loading a CSV and looking at it
- Selecting and filtering rows and columns
- Cleaning: missing values, duplicates and types
- Group by, merge, concat and pivot tables
- Train and test split and turning text into numbers
- Training a first model with scikit-learn

Good to know: Fit scalers and encoders on the training set only, then apply them to the test set. If the training score is far better than the test score, the model is overfitting.
