Unlike parameters, finding hyperparameters in training data is unattainable. As such, to find the right hyperparameters, we create a model for each combination of hyperparameters.

WebGridSearchCV inherits the methods from the classifier, so yes, you can use the .score, .predict, etc.. methods directly through the GridSearchCV interface. If you wish to extract the best hyper-parameters identified by the grid search you can use .best_params_ and this will return the best hyper-parameter.
