Spyder is a comprehensive IDE designed for scientific programming with features like variable exploration and integrated debugging tools, making it ideal for data analysis and development. In contrast, IPython offers a more interactive and flexible command-line interface perfect for quick prototyping and exploratory data analysis, but lacks some of the IDE features that Spyder provides.
