data = pd. Read_csv('your_dataset. Csv')
X = data. Drop('target_column', axis=1)
y = data['target_column'] # Split data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0. 2, random_state=42) # Initialize and train a RandomForestClassifier model
model = RandomForestClassifier(n_estimators=100, random_state=42)
model. Fit(X_train, y_train) # Make predictions and evaluate
predictions = model. Predict(X_test)
accuracy = accuracy_score(y_test, predictions)
print(f"Model Accuracy: {accuracy:. 2f}")
