| - `load_iris()`: Function that loads the popular `iris`dataset with three classes for multiclass classification. | ||
| - `train_test_split()`: Divides the dataset into training and testing subsets. | ||
| - `RandomForestClassifier()`: Algorithm that is used for multiclass classification. Other classifiers like `LogisticRegression`, `SVC`, can also be used for the same. | ||
| - `fit()`: Method used to train the model on training data. | ||
| - `predict()`: Method makes predicitions on the test data. |

You can simply add the syntax of RandomForestClassifier:

please mention that:
It demonstrates one way to effectively perform multi-class classification, while there are many algorithms in Scikit-learn for multi-class classification.
