寻求可同时兼容Pythonista与标准Python的简易2D图形库

Great question! I totally get wanting code that works seamlessly between Pythonista (such a handy tool for on-the-go coding!) and standard Python on your PC—no need to maintain two separate codebases. Here are my top recommendations for 2D graphics libraries that play nice with both environments:

1. Pygame #

• Cross-environment support: Pythonista includes an official subset of Pygame covering all core 2D drawing, input handling, and basic sprite functionality. On PC, you get the full library via pip install pygame. Most basic code runs unchanged between the two.
• Why it’s a fit: It’s beginner-friendly, has tons of tutorials, and works for everything from simple shape drawing to full 2D games.
• Quick example code:

  import pygame
  import sys
  
  # Initialize Pygame
  pygame.init()
  
  # Set up window
  screen = pygame.display.set_mode((400, 300))
  pygame.display.set_caption("Cross-Platform Test")
  
  # Main loop
  running = True
  while running:
      screen.fill((255, 255, 255))  # White background
      
      # Draw a red rectangle
      pygame.draw.rect(screen, (255, 0, 0), (50, 50, 100, 80))
      # Draw a blue circle
      pygame.draw.circle(screen, (0, 0, 255), (250, 150), 40)
      
      # Handle exit event
      for event in pygame.event.get():
          if event.type == pygame.QUIT:
              running = False
      
      pygame.display.flip()
  
  pygame.quit()
  sys.exit()
  

2. Pyglet #

• Cross-environment support: Pyglet is a lightweight, pure-Python library that works on both platforms. In Pythonista, install it via the built-in package manager (or pip install pyglet if you use Stash). On PC, just run pip install pyglet.
• Why it’s a fit: It has a clean object-oriented API, focuses on multimedia and graphics, and requires no external dependencies beyond Python itself.
• Quick example code:

  import pyglet
  
  # Create a window
  window = pyglet.window.Window(width=400, height=300, caption="Pyglet Test")
  
  @window.event
  def on_draw():
      window.clear()
      # Draw a green triangle
      pyglet.graphics.draw(3, pyglet.gl.GL_TRIANGLES,
                          ('v2f', (100, 50, 300, 50, 200, 250)),
                          ('c3B', (0, 255, 0, 0, 255, 0, 0, 255, 0))
                          )
  
  pyglet.app.run()
  

3. Turtle Graphics #

• Cross-environment support: Turtle is built into Python on both platforms—no installation needed at all! Pythonista includes the full turtle module, so your code runs exactly the same on PC and iOS.
• Why it’s a fit: It’s incredibly simple to learn, perfect for drawing basic geometric shapes, patterns, or fractals. Great for quick prototyping or teaching concepts.
• Quick example code:

  import turtle
  
  # Create a turtle object
  t = turtle.Turtle()
  t.speed(2)
  
  # Draw a square
  for _ in range(4):
      t.forward(100)
      t.right(90)
  
  # Move to a new position and draw a spiral
  t.penup()
  t.goto(-150, 0)
  t.pendown()
  for i in range(50):
      t.forward(i * 2)
      t.right(20)
  
  turtle.done()
  

Pro Tip for Minor Environment Differences #

Occasionally, you might need to tweak code for small platform-specific quirks (like window sizing in Pythonista). Add a simple check to handle this:

import sys
is_pythonista = sys.executable.lower().endswith('pythonista3')

# Example: Adjust window size for Pythonista
if is_pythonista:
    window_size = (350, 280)
else:
    window_size = (400, 300)

All these libraries let you create simple 2D graphics without rewriting code for Pythonista vs. standard Python. Pick the one that best matches your project’s complexity!
