As you continue your journey with **SciPy**, it is important to develop the ability to identify which submodules are best suited for different scientific programming tasks. **SciPy** is organized into specialized submodules, each targeting a particular area such as optimization, integration, linear algebra, and more. By practicing how to import these submodules correctly, you build the foundation for efficient and accurate scientific computing.
