How can I use Cython to speed up my Python code?

Cython is a programming language that makes writing C extensions for Python as easy as Python itself. You can use it to compile Python code into C, which can significantly improve performance.

What are the steps to convert a Python function to Cython?

First, you need to install Cython. Then, create a .pyx file with your Python code, add type declarations, and compile it using a setup.py script.

Can you give me an example of a simple function in Cython?

Sure! Here's a simple example:

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

This function adds two integers and is much faster than a pure Python version.

Are there any limitations to using Cython?

Yes, Cython can be less flexible than pure Python, especially with dynamic typing. Some Python features may not work as expected.
