python圣诞树代码编程

python圣诞树代码编程_第1张图片

以下是一个简单的Python圣诞树代码:

  1. def draw_tree(height):
  2.     for i in range(height):
  3.         print(' ' * (height - i - 1) + '*' * (2 * i + 1))
  4.     print(' ' * (height - 1) + '|')
  5. draw_tree(10)

这个函数会绘制一个等腰三角形,其中每一行的星号数量从1开始,每次递增2,空格数量则相反,从等腰三角形的高度减1开始,每次递减1。最后一行输出一个竖线,表示圣诞树的树干。你可以根据需要调整高度来改变圣诞树的大小。

这段代码只是绘制了一个基本的圣诞树形状,你可以进一步扩展它,让圣诞树更加生动和有趣。例如,你可以使用Python的turtle模块,绘制一个会动的圣诞树。

以下是一个使用turtle模块的Python圣诞树代码:

  1. import turtle
  2. def draw_tree(height):
  3.     tree = turtle.Turtle()
  4.     tree.penup()
  5.     tree.goto(0, -height)
  6.     tree.pendown()
  7.     tree.color('green')
  8.     for i in range(height):
  9.         tree.forward(2)
  10.         tree.right(144)
  11.         tree.forward(4)
  12.         tree.right(144)
  13.         tree.forward(2)
  14.         tree.right(144)
  15.         tree.forward(4)
  16.         tree.right(144)
  17.     tree.right(90)
  18.     tree.forward(height * 2)
  19.     tree.right(90)
  20.     tree.forward(height)
  21.     tree.right(90)
  22.     tree.forward(height)
  23.     tree.right(90)
  24.     tree.forward(height * 2)
  25.     tree.right(90)
  26.     tree.forward(height)
  27.     tree.right(90)
  28.     tree.forward(height)
  29.     tree.right(90)
  30.     tree.forward(height * 2)
  31.     tree.right(90)
  32.     tree.forward(height)
  33.     tree.right(90)
  34.     tree.forward(height)
  35.     tree.right(90)
  36.     tree.forward(height * 2)
  37.     tree.right(90)
  38.     tree.forward(height)
  39.     tree.right(90)
  40.     tree.forward(height)
  41.     tree.right(90)
  42.     tree.forward(height * 2)

当然,我们可以进一步增加代码的复杂性和视觉效果。例如,我们可以使用Python的Pygame库来创建一个更加生动和有趣的圣诞树。

以下是一个使用Pygame库的Python圣诞树代码:

  1. import pygame
  2. import math
  3. # 初始化Pygame
  4. pygame.init()
  5. # 设置屏幕大小和标题
  6. screen = pygame.display.set_mode((800, 600))
  7. pygame.display.set_caption("Christmas Tree")
  8. # 设置颜色
  9. green = (0, 255, 0)
  10. red = (255, 0, 0)
  11. brown = (100, 50, 0)
  12. yellow = (255, 255, 0)
  13. white = (255, 255, 255)
  14. black = (0, 0, 0)
  15. # 绘制圣诞树函数
  16. def draw_tree(x, y, height, width):
  17.     pygame.draw.line(screen, green, (x, y), (x + width // 2, y + height), 10)
  18.     pygame.draw.line(screen, green, (x + width // 2, y + height), (x + width, y), 10)
  19.     pygame.draw.line(screen, green, (x + width // 2, y), (x + width // 2, y + height), 10)
  20.     pygame.draw.polygon(screen, green, [(x + width // 4, y + height // 4), (x + width * 3 // 4, y + height // 4), (x + width // 2, y + height), (x + width // 4, y + 3 * height // 4)])
  21.     pygame.draw.polygon(screen, green, [(x + width // 4, y), (x + width * 3 // 4, y), (x + width // 2, y + height // 2), (x + width // 4, y + height // 4)])
  22.     pygame.draw.polygon(screen, green, [(x + width // 4, y + height // 2), (x + width * 3 // 4, y + height // 2), (x + width // 2, y + height), (x + width // 4, y + 3 * height // 4)])
  23.     pygame.draw.line(screen, green, (x + width // 4, y + height), (x + width // 4 - height // 4 * math.tan(math.pi / 6), y + height // 2), height // 8 * math.cos(math.pi / 6))
  24.     pygame.draw.line(screen, green, (x + width // 4, y + height), (x + width // 4 - height // 8 * math.tan(math.pi / 6), y + height - height // 4), height // 8 * math.cos(math.pi / 6))
  25.     pygame.draw.circle(screen, brown, (x + width // 4 - height // 8 * math.tan(math.pi / 6), y + height - height // 4), height // 8)
  26.     pygame.draw.circle(screen, brown, (x + width //
