python使用turtle库绘制树

本文实例为大家分享了python使用turtle库绘制树的具体代码，供大家参考，具体内容如下

# -*- coding: utf-8 -*-"""Spyder EditorThis is a temporary script file."""import turtle, datetime 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(d): #根据数字绘制七段数码管   drawLine(True) if d in [2,3,4,5,6,8,9] else drawLine(False)   drawLine(True) if d in [0,1,3,4,5,6,7,8,9] else drawLine(False)   drawLine(True) if d in [0,2,3,5,6,8,9] else drawLine(False)   drawLine(True) if d in [0,2,6,8] else drawLine(False)   turtle.left(90)   drawLine(True) if d in [0,4,5,6,8,9] else drawLine(False)   drawLine(True) if d in [0,2,3,5,6,7,8,9] else drawLine(False)   drawLine(True) if d in [0,1,2,3,4,7,8,9] else drawLine(False)   turtle.left(180)   turtle.penup()   turtle.fd(20) def drawDate(date):   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(-350)   turtle.pensize(5)   drawDate(datetime.datetime.now().strftime('%Y-%m=%d+'))   turtle.hideturtle() main()
