Moving Two Rectangles in Pygame

Question

I'm trying to make a game and encountered a problem...I can't move the rectangle of player2. The two rectangles are all from the same class

import pygame,sys
#........
class player(object):
    def __init__(self,determination,x1,x2):
        if determination:
            self.rect = pygame.rect.Rect([x1,0,40,5])
        elif determination == 0:
            self.rect = pygame.rect.Rect([x2,475,40,5])
    
    def draw(self,surface,color):
            pygame.draw.rect(screen,color,self.rect,1)

    def handle_keys(self,determination):
        for event in pygame.event.get():
            if event.type ==  pygame.KEYDOWN:
                if event.key == pygame.K_a and determination:
                    self.rect.left = self.rect.left -3
                    self.rect.right = self.rect.right - 3
                elif event.key == pygame.K_d and determination:
                    self.rect.right = self.rect.right + 3
                    self.rect.left = self.rect.left+ 3
                elif event.key == pygame.K_LEFT and determination == 0:
                    self.rect.left = self.rect.left -3
                    self.rect.right = self.rect.right - 3
                elif event.key == pygame.K_RIGHT and determination == 0:
                    self.rect.right = self.rect.right + 3
                    self.rect.left = self.rect.left+ 3


    player1.handle_keys(1)
    player2.handle_keys(0)
    player1.draw(screen,color1)
    player2.draw(screen,color2)
    #.......

pygame.event.get() get all the messages and remove them from the queue. If pygame.event.get() is called in multiple event loops, only one loop receives the events, but never all loops receive all events. As a result, some events appear to be missed.

Get the events once and use them in multiple loops or pass the list or events to functions and methods where they are handled:

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

    def handle_keys(self,determination, event_list):
        for event in event_list:
            # [...]

while True:

    event_list = pygame.event.get()

    # [...] 

    player1.handle_keys(1, event_list)
    player2.handle_keys(0, event_list)

    # [...]
