I keep getting the error: TypeError: integer argument expected, got float in Python 3.6.5

I am using Python version 3.6.5, downloaded from Python.org. While programming, I keep getting the error TypeError: integer argument expected, got float. I am using Python version 3.6.5, win 32 bit. Here is my complete code yet (to be worked on still):

TypeError: integer argument expected, got float

import pygame

pygame.init()

black = (0,0,0)
white = (255,255,255)
red = (255,0,0)
blue = (0,0,255)
sky_blue = (0,150,225)
green = (0,255,0)

displayWidth = 800

displayHeight = 600
#Final :- pygame.display.set_mode((1365, 1050))
gameDisplay = pygame.display.set_mode((displayWidth,displayHeight))
pygame.display.set_caption('Super Mario')
clock = pygame.time.Clock()

crashed = False

timeOut = False

Quit = False

#50,75
marioStanding = pygame.image.load('Super_Mario_Standing.jpg')
marioStanding = pygame.transform.scale(marioStanding, (displayWidth/40,displayHeight/8))

def Stand(x,y):
gameDisplay.blit(marioStanding,(x,y))

x = (displayWidth * 0.45)
y = (displayHeight * 0.8)

while not crashed and not timeOut and not Quit:

for event in pygame.event.get():
if event.type == pygame.QUIT:
Quit = True

print (event)

gameDisplay.fill(sky_blue)
Stand(x,y)

pygame.display.update()
clock.tick(24)

pygame.quit()
quit()


I was not getting any error before removing the height and width as 50,75, and replacing it with displayWidth/40, displayHeight/8, so I'm guessing that it has something to do with that. Here is the full error:

50,75

displayWidth/40, displayHeight/8

Traceback (most recent call last):
File "C:UsersDellDesktopSuper_Mario_Python3.6Billionth_Pygame_Test.py", line 28, in <module>
marioStanding = pygame.transform.scale(marioStanding, (displayWidth/40,displayHeight/8))

Welcome to python 3 floating point division. Here:

pygame.transform.scale(marioStanding, (displayWidth/40,displayHeight/8))


your divisions, even if made between integers, create a tuple of float elements.

>>> 200/40
5.0


Use integer division to keep them as integers (this wasn't the case in python 2) so the scale function accepts them as arguments.

scale

>>> 200//40
5


like this:

pygame.transform.scale(marioStanding, (displayWidth//40,displayHeight//8))


Note: it also works in python 2.
