What are the differences between Python extensions and modules?

What are the differences between Python extensions and modules?

Python extensions are typically written in C or C++ and allow for performance optimization, while modules are written in Python and are used to organize code.

Can you give me an example of a Python extension?

Sure! An example of a Python extension is NumPy, which is written in C and provides support for large, multi-dimensional arrays and matrices.

How do I create a simple Python module?

To create a simple Python module, just write your functions in a .py file. For example, create a file named mymodule.py and define your functions there.

Are there any performance benefits to using extensions?

Yes, using extensions can significantly improve performance for computationally intensive tasks, as they run closer to the hardware.
