作为一个Python初学者，我想通过写博客的方式来记录下来自己成长的过程，同时也分享一下自己学习到的知识。以下都是一个Python初学者对Python语言的一些浅见和个人理解。
基本操作
import turtle #导入turtle模块
turtle.width(10) #改变画笔宽度
turtle.showturtle() #显示箭头
turtle.write(“hahaha”) #写字符串
turtle.forward(300) #前进300像素
turtle.color(“red”) #画笔颜色改为red
turtle.left(90) #箭头左转90度
turtle.forward(300)
turtle.goto(0,50) #去坐标(0,50)
turtle.goto(0,0)
turtle.penup() #抬笔
turtle.goto(0,300)
turtle.pendown() #下笔
turtle.circle(100) #画圆
练习1
#绘制奥运五环
import turtle
turtle.width(10)
turtle.color(“blue”)
turtle.circle(50)
turtle.penup()
turtle.goto(110,0)
turtle.pendown()
turtle.color(“black”)
turtle.circle(50)
turtle.penup()
turtle.goto(220,0)
turtle.pendown()
turtle.color(“red”)
turtle.circle(50)
turtle.penup()
turtle.goto(55,-60)
turtle.pendown()
turtle.color(“yellow”)
turtle.circle(50)
turtle.penup()
turtle.goto(165,-60)
turtle.pendown()
turtle.color(“green”)
turtle.circle(50)
练习2
#定义多点坐标，绘制折线，并计算起始点和终点距离
import turtle
import math
#定义多点坐标
x1,y1 = 100,100
x2,y2 = 80,80
x3,y3 = 100,-100
x4,y4 = 80,-80
x5,y5 = -100,-100
x6,y6 = -80,-80
x7,y7 = -100,100
x8,y8 = -80,80
#绘制折线
turtle.penup()
turtle.goto(x1,y1)
turtle.pendown()
turtle.goto(x2,y2)
turtle.goto(x3,y3)
turtle.goto(x4,y4)
turtle.goto(x5,y5)
turtle.goto(x6,y6)
turtle.goto(x7,y7)
turtle.goto(x8,y8)
#计算距离
distance = int(math.sqrt((x1-x4)**2 + (y1-y4)**2))
turtle.color(“red”)
turtle.write(distance)
