如何用Python画一个圣诞树呢?
最简单:
1height =5
2
3stars =1
4for i inrange(height):
5print((' '* (height - i)) + ('*'* stars))
6stars +=2
7print((' '* 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。
方法一:
1import turtle
2screen = turtle.Screen()
3screen.setup(800,600)
4circle = turtle.Turtle()
5circle.shape('circle')
6circle.color('red')
7circle.speed('fastest')
8circle.up()
9square = turtle.Turtle()
10square.shape('square')
11square.color('green')
12square.speed('fastest')
13square.up()
14circle.goto(,280)
15circle.stamp()
16k =
17for i inrange(1,17):
18y =30*i
19forj inrange(i-k):
20x =30*j
21square.goto(x,-y+280)
22square.stamp()
23square.goto(-x,-y+280)
24square.stamp()
25ifi %4==:
26x =30*(j+1)
27circle.color('red')
28circle.goto(-x,-y+280)
29circle.stamp()
30circle.goto(x,-y+280)
31circle.stamp()
32k +=2
33ifi %4==3:
34x =30*(j+1)
35circle.color('yellow')
36circle.goto(-x,-y+280)
37circle.stamp()
38circle.goto(x,-y+280)
39circle.stamp()
40square.color('brown')
41for i inrange(17,20):
42y =30*i
43forj inrange(3):
44x =30*j
45square.goto(x,-y+280)
46square.stamp()
47square.goto(-x,-y+280)
48square.stamp()
49turtle.exitonclick()
效果:
方法二:
1from turtleimport*
2import random
3import time
4
5n =80.0
6
7speed("fastest")
8screensize(bg='seashell')
9left(90)
10forward(3*n)
11color("orange","yellow")
12begin_fill()
13left(126)
14
15for i inrange(5):
16forward(n/5)
17right(144)
18forward(n/5)
19left(72)
20end_fill()
21right(126)
22
23color("dark green")
24backward(n*4.8)
25def tree(d, s):
26ifd
27forward(s)
28tree(d-1, s*.8)
29right(120)
30tree(d-3, s*.5)
31right(120)
32tree(d-3, s*.5)
33right(120)
34backward(s)
35tree(15, n)
36backward(n/2)
37
38for i inrange(200):
39a =200-400* random.random()
40b =10-20* random.random()
41up()
42forward(b)
43left(90)
44forward(a)
45down()
46ifrandom.randint(,1) ==:
47color('tomato')
48else:
49color('wheat')
50circle(2)
51up()
52backward(a)
53right(90)
54backward(b)
55time.sleep(60)
效果:
好了,我要先去画圣诞树啦~祝大家圣诞节快乐!!!
