done()1、 First of all, I apologize to you , How to draw candy , I have no better idea , Then the painting was very depressing , In the end, the whole function has not been improved , The placement position and size have been set , But angle because I press -10 To design the drawing method , So it can only draw -10 Degrees of candy , But it should be easy to adjust , I just have to add range Then adjust it again , The reader needs to revise it himself ！
2、 All the pendants , Except candy , Coordinates are set 、 The placement angle and size are three , You can use this function to put the pendant in the right place , Decorate your own Christmas tree .
3、 Reference source ： use Python Draw a Christmas tree , Referring to the author's tree drawing , And the code is optimized , Because the latter author's Pendant writing method is completely difficult for me to understand , Therefore, on this basis, it is modified into .
4、 Because my art level and coding level are limited , The picture of the pendant is not very beautiful , Let's make do with it , I also hope you can decorate our trees better ！
5、turtle Library is learning and doing now , The algorithm is not very good , Please correct the imperfections under the guidance of the boss ！
