Pinhole Camera?

I would like to know if the default camera generated by blender 2.9 is based on the pinhole model, or if I can apply this model to it? If not, how can I generate a pinhole camera with blender?

I saw a post where someone generated one with Blender like an object. However, I would like to know how to do this using python.

Thank you for your answer. Have a lovely day and weekend.
