width = surface.get_size()[0]
height = surface.get_size()[1]

import pygame as pg
pg.init()

rect = pg.Rect(x,y,width = 100, height = 50)
# method 1, returns a tuple of width and height
>>> print(rect.get_size())
(100,50)
# method 2, returns a specific value
>>> print(rect.get_width())

>>> print(rect.get_height())
