Certain functions being assigned to variables

Why are some functions like so my_file = open(“my.file”,”r”) assigned to variables? I thought about this when looking at the Pygame module, as it has a certain function to create a surface that was put in an example like this: Win = pygame.display.set_mode((500,500)) I don’t know why I brought that up, but you hopefully get what I mean.

Because they return a value. Then you can assign the returned value to a variable-in other languages- of the same type.

so what would be the value of the first example? The contents of the file?

You should check what open() returns and what functionality is available to that object.

But it is not just an string. Its an object with some methods contained within, so that you can do things with it.
