How do I get started with Cython?

To get started with Cython, first, ensure you have Python and Cython installed. You can install Cython using pip: pip install cython.

What are the basic steps to create a Cython file?

Create a .pyx file for your Cython code. Then, write your Python code in that file, and compile it using a setup script.

Can you show me a simple example?

Sure! Here's a simple example:

# example.pyx
def say_hello():
    print('Hello from Cython!')

You can compile it with a setup script.

What do I need in the setup script?

Your setup script should look like this:

from setuptools import setup
from Cython.Build import cythonize

setup(ext_modules=cythonize('example.pyx'))

Run it with python setup.py build_ext --inplace.
