Help me figure out the license please

[Ярослав Тамбовский]

Hello, I am a 16 year old aspiring developer from Russia. I would like to use PyQT to write a program for a desktop to control routers (School project) I know that I can use a library for open source and free code, but can I send this program to competitions and Olympiads? (After all, there I can get an award) Can an educational institution use my program within its walls?
Best wishes, Yaroslav.
P.S. I tried to figure out the license myself, but I didn't succeed. Please forgive me for distracting you from work.
