How to find the prize in the text of the contest description?

Question

Python

I have an array of contest descriptions. I want to automatically receive from future descriptions of competitions what prize is offered (for now, if there are several prizes, it is enough to find one). How to approach this task?
It is clear that the current array must be marked - manually select the prizes. What is the minimum number of tenders to process manually? And then what to do with it?
