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. Would you like a simple example?

Yes, please provide a basic example of using Cython.

Sure! First, install Cython using pip. Then, create a file named example.pyx with the following code:

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

Next, create a setup.py file to compile it:

from setuptools import setup
from Cython.Build import cythonize

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

Run python setup.py build_ext --inplace to compile it.

How do I call the compiled function in my Python code?

After compiling, you can import the function in your Python code like this:

from example import add
result = add(5, 3)
print(result)  # Output will be 8
