How to generate an empty image?

Question

Python

Hello! The frontend uses an empty image (as a placeholder so that the content does not move out when loading images) for lazy load loading of images. There is a service that generates this empty image. Using its API is unwise, because. extra requests from the backend server. How can I generate this empty image using python?

empty image example
