What is Cython and how can it help with Python extensions?

Cython is a programming language that makes writing C extensions for Python as easy as Python itself. It allows you to gain C-like performance with code that is mostly written in Python.

Can you give me an example of how to use Cython?

Sure! You can create a simple Cython file, say example.pyx, and define a function like this:

def add(int a, int b):
    return a + b

Then, you compile it using a setup script.

What are the benefits of using Cython over pure Python?

Cython can significantly speed up your code execution, especially in computationally intensive tasks, by compiling to C. It also allows for better integration with C libraries.

Are there any limitations I should be aware of?

Yes, while Cython is powerful, it requires some understanding of C types and may not be as straightforward for pure Python code. Also, not all Python features are supported.
