Sklearn GridSearchCV (in Python) - Cross-Validation in Scikit-learn

## What is GridSearchCV

GridSearchCV tests different hyperparameter values to find the best one for your model.

You should use GridSearchCV instead of KFold and cross_val_score when you're not only looking to evaluate a model but also want to tune hyperparameters to find the best combination for your model.

## How GridSearchCV Works

- GridSearchCV splits the training data in k equal parts (folds).
- Each fold is used as a validation set and the remaining is used as training
