Can you post sites with olympiad problems in python?

Question

Python

For a year now, I have been slowly studying python, I learned the theory, but there is no special practice, so to speak. I'm not working yet, so I need sites with such fat tasks. Not something like calculating simple percentages and other simple algorithms, but so that there is an emphasis on algorithms that are different and more complicated. Does anyone have a list and can share?
