Python小练习

1.绘制一条蟒蛇

 1 #snake.py
 2 from turtle import *
 3 setup(0.8, 0.8, 0, 0)
 4 penup()
 5 fd(-250)
 6 pendown()
 7 pensize(25)
 8 pencolor("blue")
 9 seth(-40)
10 for i in range(3):
11     circle(40, 80)
12     circle(-40, 80)
13 circle(40, 80/2)
14 fd(40)
15 circle(16, 180)
16 fd(40 * 2/3)

2.同心圆

 1 from turtle import *
 2 a = 10
 3 pencolor("red")
 4 for i in range(0, 5):
 5     penup()
 6     goto(0, -10 * i)
 7     pendown()
 8     circle(a)
 9     a += 10
10 hideturtle()
11 done()

3.九九乘法表

1 # 3.九九乘法表
2 print("3.九九乘法表".center(20, '-'))
3 for i in range(1, 10):
4     for j in range(1, i+1):
5         print("{}*{}={:2}".format(j, i, i*j), end=' ')
6     print(' ')

4.1-10的阶乘之和

1 #计算1-10的阶乘之和
2 sum,tmp=0,1
3 for i in range(1,11):
4     tmp*=i
5     sum+=tmp
6 print("运算结果是：{}".format(sum))

5.1-N求和

1 #2.整序列求和
2 print("2.整数序列求和".center(20,'-'))
3 n=eval(input("请输入正整数N："))
4 sum=0
5 for i in range (int(n)):
6     sum+=i+1
7 print("Sum={}".format(sum))
8 print('-'*40)

6.BMI健康指数

 1 height=weight=0.0
 2 g,z="",""
 3 height,weight= eval(input('\r请输入您的身高(m),体重(kg)[用逗号间隔,身高体重都不可为0]:'))
 4 BMI  = float(float(weight)/(float(height)**2))
 5 if BMI <18.5:
 6    g=z="偏瘦"
 7 elif 18.5<= BMI<24:  
 8    g=z="正常"
 9 elif 24<= BMI<25:   
10    g,z="正常","偏胖"
11 elif 25<= BMI <28:    
12    g=z="偏胖"
13 elif 28<=BMI <30:
14     g,z="偏胖","肥胖"
15 else:
16     g=z="肥胖" 
17 print("您的BMI测试结果:\n\tBMI指数：{:.2f}\n\t国际：{}\n\t中国：{}".format(BMI,g,z))

7.五角星的绘制

1 from turtle import *
2 fillcolor("red")
3 begin_fill()
4 while True:
5     forward(200)
6     right(144)
7     if abs(pos())<1:
8         break
9 end_fill()
