python pygame animation works without class but as soon as i put it into a class it doesnt want to work?

Question

okay, so basically i have this game that im making and before i put it into Object Oriented Programming with classes, it worked perfectly fine, the animation worked when moving, but as soon as i changed it into Object Oriented Programming, my character moves but no animation, he also goes invisible when he moves, only appears when i stop pressing a movement button please help

heres the code:

import time
import pygame
pygame.init()

win = pygame.display.set_mode((1280,720)) #creates a window size of 640 x 480 pixels

pygame.display.set_caption("World of Python") #The caption of the window is "World of Python"
pygame.transform.scale(pygame.image.load('R1.png'), (40, 60))
pygame.transform.scale(pygame.image.load('R2.png'), (40, 60))
pygame.transform.scale(pygame.image.load('R3.png'), (40, 60))
pygame.transform.scale(pygame.image.load('L1.png'), (40, 60))
pygame.transform.scale(pygame.image.load('L2.png'), (40, 60))
pygame.transform.scale(pygame.image.load('L3.png'), (40, 60))
pygame.transform.scale(pygame.image.load('U1.png'), (40, 60))
pygame.transform.scale(pygame.image.load('U2.png'), (40, 60))
pygame.transform.scale(pygame.image.load('U3.png'), (40, 60))
pygame.transform.scale(pygame.image.load('D1.png'), (40, 60))

There are 2 Indentation issues. The 1st is in player.draw:

class player(object):
    # [...]

    def draw(self,win):

        if self.moveCount + 1 >= 9: 
            self.moveCount = 0

        #<--| INDENTATION !!!
        if self.left:
                win.blit(moveLeft[self.moveCount//3], (self.x,self.y)) 
                self.moveCount += 1
        elif self.right:
            # [...]

The 2nsd one is in the main loop:

run = True
while run:
    # [...]

    else:       #this is incase the player is not moving
        man.left = False
        man.right = False
        man.up = False
        man.down = False
        man.moveCount = 0

    #<--| INDENTATION !!!
    redrawGameWindow()

Furthermore, the pygame.transform.scale instructions at the begin of the code are useless, because pygame.transform.scale. does not scale the surface itself, it returns a new scaled surface.

Change th code as follows (str converts the number to a string):

moveRight = [pygame.transform.scale(pygame.image.load('R' + str(i+1) + '.png'), (40, 60)) for i in range(3)]
moveLeft  = [pygame.transform.scale(pygame.image.load('L' + str(i+1) + '.png'), (40, 60)) for i in range(3)]
moveUp    = [pygame.transform.scale(pygame.image.load('U' + str(i+1) + '.png'), (40, 60)) for i in range(3)]
moveDown  = [pygame.transform.scale(pygame.image.load('D' + str(i+1) + '.png'), (40, 60)) for i in range(3)]
character = pygame.transform.scale(pygame.image.load('D2.png'), (40, 60))
