AI models. The key factors contributing to Python’s popularity in machine learning are: Extensive Libraries: Python offers a wide range of pre-built machine learning frameworks, such as TensorFlow, PyTorch, and Scikit-learn, which simplify the process of model development by providing pre-implement...
