Python is the most popular language for machine learning due to its simplicity, readability, and vast ecosystem of libraries. Using Python, developers and data scientists can implement machine learning models efficiently with tools like NumPy and Pandas for data manipulation, Matplotlib and Seaborn for visualization, and powerful libraries like Scikit-learn for classical ML algorithms (e.g., regression, classification, clustering). For advanced tasks like deep learning, Python supports frameworks like TensorFlow, Keras, and PyTorch. From data preprocessing to model training, evaluation, and deployment, Python offers a complete, scalable solution for building intelligent systems across industries.
