用Python绘制蟒蛇小程序

import turtledef drawSnake (rad,angle,len,neckrad):    for i in range(len):        turtle.circle(rad,angle)        turtle.circle(-rad,angle)    turtle.circle(rad,angle/2)    turtle.fd(rad)    turtle.circle(neckrad+1,180)    turtle.fd(rad*2/3)def main():    turtle.setup(1300,800,0,0)    pythonsize=30    turtle.pensize(pythonsize)    turtle.pencolor("blue")    turtle.seth(-40)    drawSnake(40,80,5,pythonsize/2)main()

运行结果：

温度转换程序：

#温度转换a = input ("请输入带温度表示的符号的温度值：")if a[-1] in ['C','c']:    f=1.8*float(a[0:-1])+32    print("转换后的温度为%.2fF："%f)elif a[-1] in ['F','f']:    c=(float(a[0:-1])-32)/1.8    print("转换后的温度为：%.2fC"%c)else:    print("输入有误")
