How to Draw Rectangles in Pygame Using `pygame.draw.rect`?

Drawing Rectangles with Pygame

In Python's Pygame library, creating rectangles is an essential task for developing games.

For Pygame versions like 3.2, drawing rectangles involves using the pygame.draw.rect function. Here's how you can achieve this:

1. Import Pygame and essential constants:

<code class="python">import pygame, sys
from pygame.locals import *</code>

2. Initialize Pygame:

<code class="python">pygame.init()</code>

3. Create a display window:

<code class="python">DISPLAY=pygame.display.set_mode((500,400),0,32)</code>

4. Set colors:

<code class="python">WHITE=(255,255,255)
BLUE=(0,0,255)</code>

5. Fill the display with white:

<code class="python">DISPLAY.fill(WHITE)</code>

6. Draw a blue rectangle using pygame.draw.rect:

<code class="python">pygame.draw.rect(DISPLAY,BLUE,(200,150,100,50))</code>

7. Start the game loop:

<code class="python">while True:
    # Handle events
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
    # Update the display
    pygame.display.update()</code>

This sample code creates a white window with dimensions of 500 pixels wide and 400 pixels high and places a blue rectangle with coordinates (200, 150) and dimensions of 100 pixels wide and 50 pixels high.
