What is a context?

This is a thing that i’ve been stumbleing upon for a while now i tried to make something in python with pygame and you start with the pygame.init function, same story with opengl in c++ you have to generate a opengl context, today i made a small bot for discord same thing .but what is it?? my only understanding of it is that you just call the function and the compiler/interpreter goes “alright fam i got you”
