I have the code below saved as a python file on my computer, but when I try to run it in the terminal all it says is "Hello Welcome to the Pygame Community". Can you please help me debug it?

import pygame

import os
os.environ['SDL_VIDEODRIVER'] = 'dummy'

# Initialize Pygame
pygame.init()

# Set window size and colors
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600
win = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
win.fill((0, 0, 0))

# Set up game variables
PONG_WIDTH = 10
PONG_HEIGHT = 60
PONG_VELOCITY_X = 10
PONG_VELOCITY_Y = 10
PADDLE_VELOCITY = 10

# Initialize positions
PONG_X = WINDOW_WIDTH // 2
PONG_Y = WINDOW_HEIGHT // 2
PADDLE1_X = 20
PADDLE1_Y = WINDOW_HEIGHT // 2 - PONG_HEIGHT // 2
PADDLE2_X = WINDOW_WIDTH - 30
PADDLE2_Y = WINDOW_HEIGHT // 2 - PONG_HEIGHT // 2

# Initialize velocities
pong_vel_x = PONG_VELOCITY_X
pong_vel_y = PONG_VELOCITY_Y

# Initialize scores
score_player1 = 0
score_player2 = 0

# Set up timer and loop
clock = pygame.time.Clock()
running = True

# Set up font
font = pygame.font.Font(None, 36)

while running:
    # Check for event inputs
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    keys = pygame.key.get_pressed()
    if keys[pygame.K_UP]:
        PADDLE2_Y -= PADDLE_VELOCITY
    if keys[pygame.K_DOWN]:
        PADDLE2_Y += PADDLE_VELOCITY
    if keys[pygame.K_w]:
        PADDLE1_Y -= PADDLE_VELOCITY
    if keys[pygame.K_s]:
        PADDLE1_Y += PADDLE_VELOCITY

    # Move the ball
    PONG_X += pong_vel_x
