Train-test-split is an important part of testing how well a model performs by training it on designated training data and testing it on designated testing data. This way, the model's ability to generalize to new data can be measured. In sklearn, both lists, pandas DataFrames, or NumPy arrays are accepted in X and y parameters. Training a standard supervised learning model takes the form of an import, the creation of an instance, and the fitting of the model.
