How to implement image creation through python?

Question

Python

How can I implement the creation of images through python, as well as their processing ...
A specific example, to make it clear:
For example, there is a two-dimensional array, where each element is a color code of a pixel of a picture, and through a function this array is converted into an image, with the ability scaling (like instead of one element of the array - 4 identical pixels), and you can also convert the image into a two-dimensional array with which you can work ...
Perhaps there are some libraries for this, or for something similar ...

Answer 1

Pillow.
Yes, no one scales like that, for a long time there are ready-made heaped algorithms
PS oh, there is also a woodpecker, it didn’t get there in a year How to draw a pixel image in Python?
