How to check if a variable contains a rect in Pygame? [duplicate]

Question

So if I add a rect to a variable like so

box = pygame.Rect(x, y, w, h)

How do I check if the variable rect holds a pygame.Rect? Ideally it would return something similar to this

int = 9 #int is not a rect #box is a rect

I'm wondering when you will need it. if you create variable to keep Rect then it should always keep Rect - don't mess it. And if you want to keep different objects on list - ie. Player, Enemy, etc. then all of them should have exactly the same methods - draw, update, etc. instead of draw_player, draw_enemy, update_player, update_enemy - and then you don't have to check class to decide if you have to use draw_player or draw_enemy - you always has to use draw. — furas

Oh I have mine for functions. I have an optional argument for centering, and I want it to automatically center stuff if a rect is passed. — bad_coder

Return True if the object argument is an instance of the classinfo argument [...]

if isinstance(box, pygame.Rect): print('is a rect') else: print('is not a rect')
