今天在慕课网上继续学习北京理工大学老师讲的Python语言程序设计,看到这个例子感觉很有趣。所以想了想还是写上来。
七段数码管绘制:
所用的知识:turtle库和time库的使用、函数的定义及使用
代码如下:
#绘制七段数码管
import turtle
import time
def drawGap():#绘制数码管间隔
turtle.penup()
turtle.fd(5)
def drawLine(draw): #绘制单段数码管
drawGap()
turtle.pendown()if draw else turtle.penup()
turtle.fd(40)
drawGap()
turtle.right(90)
def drawDigit(digit): #根据数字绘制数码管
drawLine(True) if digit in [2,3,4,5,6,8,9] else drawLine(False)
drawLine(True) if digit in [0,1, 3, 4, 5,6,7, 8, 9] else drawLine(False)
drawLine(True) if digit in [0,2,3,5,6,8,9] else drawLine(False)
drawLine(True) if digit in [0,2,6,8] else drawLine(False)
turtle.left(90)
drawLine(True) if digit in [0,4,5,6,8,9] else drawLine(False)
drawLine(True) if digit in [0,2,3,5,6,7,8,9] else drawLine(False)
drawLine(True) if digit in [0,1,2,3,4,7,8,9] else drawLine(False)
turtle.left(180)
turtle.penup()
turtle.fd(20)
def drawDate(date): #date为日期,数据格式为%Y-%m=%d+
turtle.pencolor('red')
for i in date:
if i == '-':
turtle.write('年',font=('Arial',18,'normal'))
turtle.pencolor('green')
turtle.fd(40)
elif i == '=':
turtle.write('月',font=('Arial',18,'normal'))
turtle.pencolor('blue')
turtle.fd(40)
elif i =='+':
turtle.write('日', font=('Arial', 18, 'normal'))
else:
drawDigit(eval(i))
def main():
turtle.setup(800,350,200,200)
turtle.penup()
turtle.fd(-300)
turtle.pensize(5)
drawDate(time.strftime('%Y-%m=%d+',time.gmtime()))
turtle.hideturtle()
turtle.done()
main()
