如何用Python画一个圣诞树呢?
最简单:
height = 5stars = 1
for i in range(height):print((' ' * (height - i)) + ('*' * stars))stars += 2
print((' ' * height) + '|')
效果:
哈哈哈哈,总有一种骗了大家的感觉。
其实本文是想介绍Turtle库来画圣诞树。
import turtlescreen = turtle.Screen()
screen.setup(375, 700)circle = turtle.Turtle()
circle.shape('circle')
circle.color('red')
circle.speed('fastest')
circle.up()square = turtle.Turtle()
square.shape('square')
square.color('green')
square.speed('fastest')
square.up()circle.goto(0, 280)
circle.stamp()k = 0
for i in range(1, 13):y = 30 * ifor j in range(i - k):x = 30 * jsquare.goto(x, -y + 280)square.stamp()square.goto(-x, -y + 280)square.stamp()if i % 4 == 0:x = 30 * (j + 1)circle.color('red')circle.goto(-x, -y + 280)circle.stamp()circle.goto(x, -y + 280)circle.stamp()k += 3if i % 4 == 3:x = 30 * (j + 1)circle.color('yellow')circle.goto(-x, -y + 280)circle.stamp()circle.goto(x, -y + 280)circle.stamp()square.color('brown')
for i in range(13, 17):y = 30 * ifor j in range(2):x = 30 * jsquare.goto(x, -y + 280)square.stamp()square.goto(-x, -y + 280)square.stamp()
效果:
方法二:
import turtle# 定义圣诞树的绿叶函数
def tree(d, s):if d <= 0:returnturtle.forward(s)tree(d - 1, s * .8)turtle.right(120)tree(d - 3, s * .5)turtle.right(120)tree(d - 3, s * .5)turtle.right(120)turtle.backward(s)n = 100
""" 设置绘图速度
'fastest' : 0
'fast' : 10
'normal' : 6
'slow' : 3
'slowest' : 1
"""
turtle.speed('fastest') # 设置速度turtle.left(90)
turtle.forward(3 * n)
turtle.color("orange", "yellow")
turtle.left(126)# turtle.begin_fill()
for i in range(5):turtle.forward(n / 5)turtle.right(144)turtle.forward(n / 5)turtle.left(72)turtle.end_fill()
turtle.right(126)
turtle.color("dark green")
turtle.backward(n * 4.8)# 执行函数
tree(15, n)
turtle.backward(n / 5)
效果:
