@熊罚5327：python turtle如何画椭圆 -
应山18581221329…… 1、先搞清楚画笔的基本用法. 2、再搞清楚椭圆的函数. 3、根据别人的代码,自己多调试几次就画出有意思的图形了. 代码如下: import turtle pen=turtle.Turtle() #定义画笔实例 a=1 for i in range(120): if 0<=i<30 or 60<=i<90: a=a+0.2 pen.lt(3) #向左转3度 pen.fd(a) #向前走a的步长 else: a=a-0.2 pen.lt(3) pen.fd(a) print(pen) turtle.mainloop()
@熊罚5327：Python中Turtle模块的基本指令都有哪些 -
应山18581221329…… 通过以下方法查看turtle全部指令 In [1]: import turtle In [2]: dir(turtle)基本用法如下 import turtle turtle.forward(100) turtle.right(144) turtle.forward(100) turtle.right(144) turtle.forward(100) turtle.right(144) turtle.forward(100) turtle.right(144) turtle.forward(100)
@熊罚5327：新人求助,关于python 调用turtle -
应山18581221329…… turtle是python的简单的绘图模块,以下是一个例子from turtle import * def yin(radius, color1, color2):width(3)color(＂black＂, color1)begin_fill()circle(radius/2., 180)circle(radius, 180)left(180)circle(-radius/2., 180)end_fill()left(90)up()forward(radius*0....
@熊罚5327：使用python中的turtle画迷宫过程 -
应山18581221329…… 代码如下: import sys, math, time import turtle count = 0 def moveto(x,y): turtle.penup() turtle.goto(x,y) turtle.pendown() def hilbert(x0, y0, xi, xk, yi, yk, n): if n <= 0: X = x0 + (xi + yi)/2 Y = y0 + (xk + yk)/2 X2 = X * 600 -300 Y2 = Y * 600 -300 global count ...
@熊罚5327：初学者弱弱的问一句,python turtle graphics打开后总是未响应状态,为什么?怎么解决呢?谢谢!~ -
应山18581221329…… 如果用鼠标去点那个窗口确实会“未响应”,但是你继续在python里调命令画图是可以正常画的.
