How do I make the square and circles show up at the same time in pygame?

Question

I am trying to make a game where there are a bunch of falling circles and the player(the square) needs to avoid them. I have managed to get the controls of the player and all of the falling circles but when I press play all I see are the falling circles and no square. The only time the square shows is when I press the arrow keys. How can I make the square and circles show up at the same time?

  def __init__(self):
    red = (255, 0, 0)
    move_x = 300
    move_y = 400
    self.rect = pygame.draw.rect(apGame,red, (move_x, move_y, 10, 10))

for q in range(ballNum):
  x = random.randrange(0, width)
  y = random.randrange(0, varHeigth)
  eBall.append([x, y])

while True:
#I think this is where my problem is
  apGame.fill(black)
  player.handle_keys()

  for i in range(len(eBall)):

    pygame.draw.circle(apGame, blue, eBall[i], size)

    eBall[i][1] += 5

    if eBall[i][1] > height:

        y = random.randrange(-50, -10)
        eBall[i][1] = y

        x = random.randrange(0, width)
        eBall[i][0] = x


  pygame.display.flip()
  clock.tick(30)

If you insert a line :

player.draw_rect (0, 0)

just above

pygame.display.flip ()

then your square will show up. I would recommend using :

pygame.key.get_pressed ()

instead of :

pygame.KEYDOWN

so that your player will keep moving as long as the key is being held down instead of having to press and release the left or right keys over and over.

Edit : In response to OPs question in comments, here is working code :

import pygame
from pygame.locals import *
import random

white = (255,255,255)
blue = (0,0,255)
gravity = 10
size =10
height = 500
width =600
varHeigth = height
ballNum = 5
eBall = []
apGame = pygame.display.set_mode((width, height))
pygame.display.set_caption("AP Project")

clock = pygame.time.Clock()

class Player(object):

  def __init__(self):
    red = (255, 0, 0)
    move_x = 300
    move_y = 400
    self.rect = pygame.draw.rect(apGame,red, (move_x, move_y, 10, 10))
    self.dist = 10

  def handle_keys(self):
    for e in pygame.event.get():
      if e.type == pygame.QUIT:
        pygame.quit();
        exit()
    key = pygame.key.get_pressed ()
    if key [pygame.K_LEFT]:
      self.draw_rect(-1, 0)
    elif key [pygame.K_RIGHT]:
      self.draw_rect(1, 0)
    elif key [pygame.K_ESCAPE]:
      pygame.quit();
      exit()
    else :
      self.draw_rect (0, 0)

  def draw_rect(self, x, y):
    red = (255, 0, 0)
    black = (0, 0, 0)
    self.rect = self.rect.move(x * self.dist, y * self.dist);
    pygame.draw.rect(apGame, red , self.rect)

  def draw(self,surface):
    red = (255, 0, 0)
    move_x = 300
    move_y = 400
    pygame.draw.rect(apGame, red, (move_x, move_y, 10, 10))


move_x = 300
move_y = 400
red = (255, 0, 0)
black = (0, 0, 0)
player = Player()
clock = pygame.time.Clock()
'''apGame.fill(black)'''
player.draw(apGame)
pygame.display.update()

for q in range(ballNum):
  x = random.randrange(0, width)
  y = random.randrange(0, varHeigth)
  eBall.append([x, y])

while True:
  apGame.fill(black)
  for i in range(len(eBall)):
    pygame.draw.circle(apGame, blue, eBall[i], size)
    eBall[i][1] += 5
    if eBall[i][1] > height:
        y = random.randrange(-50, -10)
        eBall[i][1] = y
        x = random.randrange(0, width)
        eBall[i][0] = x

  player.handle_keys ()
  pygame.display.flip()
  clock.tick(30)
