===== Python Code =====
import pygame
import sys
Initialize Pygame
pygame.init()
Set the screen size
size = width, height = 300, 400
screen = pygame.display.set_mode(size)
Set the colors
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
GRAY = (128, 128, 128)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
Set the font
font = pygame.font.Font(None, 32)
Set the calculator variables
num1 = ''
num2 = ''
operator = ''
result = ''
Create the display text surface
display_text = font.render(result, True, BLACK)
display_rect = display_text.get_rect(center=(150, 50))
Create the button surfaces
button_size = (60, 60)
button_spacing = 10
button_x = (width - button_size[0] * 4 - button_spacing * 3) / 2
button_y = 120

for col in range(4):
button_rects.append(pygame.Rect(button_x + (button_size[0] + button_spacing) * col,
button_y + (button_size[1] + button_spacing) * row,
*button_size))
Set the button labels
button_labels = ['7', '8', '9', '/',
'4', '5', '6', '*',
'1', '2', '3', '-',
'C', '0', '=', '+']
Create the button text surfaces
button_text_surfaces = []
for label in button_labels:
text_surface = font.render(label, True, BLACK)
button_text_surfaces.append(text_surface)
Start the game loop
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
elif event.type == pygame.MOUSEBUTTONDOWN:
Check if a button was clicked
for i, rect in enumerate(button_rects):
if rect.collidepoint(event.pos):
Handle button click
button_label = button_labels[I]
if button_label.isdigit():
if operator:
if len(num2) < 8: # Only allow 8 digits for num2
num2 += button_label
else:
if len(num1) < 8: # Only allow 8 digits for num1
num1 += button_label
result = num1 + operator + num2

num1 = str(eval(num1 + operator + num2))
num2 = ''
operator = ''
result = num1
display_text = font.render(result[-8:], True, BLACK) # Only display the last 8 characters
break
Clear the screen
screen.fill(WHITE)
Draw the display
pygame.draw.rect(screen, GRAY, (50, 20, 200, 60))
screen.blit(display_text, display_rect)
Draw the buttons
for i, rect in enumerate(button_rects):
pygame.draw.rect(screen, BLUE, rect)
screen.blit(button_text_surfaces[i], rect.inflate(-20, -20))
Draw the number display rectangle
pygame.draw.rect(screen, BLACK, (50, 20, 200, 60), 2)
Update the screen
pygame.display.flip()
