  10. Cython is a superset of Python that allows you to write C extensions for Python in a very simple and Pythonic way. It lets you add static type declarations to your Python code, which the Cython compiler can then turn into efficient C code. When compiled, Cython code can run much faster than pure Python code, particularly for numerical calculations, loops, and other performance-critical operations. Essentially, Cython bridges the gap between Python’s high-level ease of use and the performance of C.

    Using Cython functions in IPython can significantly speed up your code execution, as demonstrated in the example where a Fibonacci sequence calculation becomes 100 times faster. This method is excellent for developers seeking efficiency. If you enjoy quick problem solving like optimizing code, you might also appreciate the fast-paced challenges in the Sprunki game, which requires sharp focus and agility to succeed.
