🌸 Iris Flower Classifier — Random Forest ML Model

A beginner-friendly machine learning project that trains a Random Forest classifier on the classic Iris dataset to predict flower species with high accuracy — covering the full ML pipeline from data loading to model evaluation.

🛠️ Technologies Used

• Python 3 — Core programming language
• pandas — Used to load and structure the dataset into a readable DataFrame
• scikit-learn — Provides the Iris dataset, train/test splitting, Random Forest model, and evaluation metrics
• matplotlib — Imported for potential data visualization support
• RandomForestClassifier — An ensemble learning model that combines multiple decision trees for accurate predictions
• accuracy_score & classification_report — Metrics used to measure how well the model performs

🔄 How It Works — Step by Step

1. Load the dataset — The built-in Iris dataset is loaded from scikit-learn and converted into a pandas DataFrame with proper column names
2. Explore the data — The first 5 rows of features (sepal length, sepal width, petal length, petal width) are printed for inspection
3. Split the data — The dataset is divided into 80% training and 20% testing using train_test_split with a fixed random_state=42 for reproducibility
4. Initialize the model — A RandomForestClassifier is created with random_state=42 to ensure consistent results across runs
5. Train the model — The model is fitted on the training data using model.fit(X_train, y_train)
6. Make predictions — The trained model predicts flower species for the unseen test data
7. Evaluate performance — accuracy_score calculates overall accuracy and classification_report breaks down precision, recall, and F1-score per class
