foreword
Today is the Dragon Boat Festival, and then yesterday I also learned about drawing, and then I wanted to see if I could draw it, but it turned out to be a bit difficult, and it is hard to describe it with CharAI. Later, I found one and changed it.
text
I still encountered a few problems when I changed it. First, I misunderstood the goto function. It used the middle of the screen as the origin. When I was learning other languages, I remembered that I used the upper left corner of the screen as the origin. Python's turtle library recognizes and learns (4) the position of the turtle (turtle.goto())
Zongye drawing
In this case, it is necessary to reflect the three-dimensional effect by first drawing the main surface and then the side. I feel that this drawing either requires a particularly clear mind, that is, where it moves, and which direction the angle is facing, or it can only be like me. After debugging, if the angle is wrong or the moving distance is wrong, it takes a long time to modify each time.
The color of my brush here is still black, and the color of the zong leaves is pure green. If the brush is also green, the painting will not feel very beautiful, and the lines will not be reflected. The front side can be written with a loop, but the sides cannot be written together if the angles are different. Here we need to save a point for the convenience of drawing encapsulation lines later.

Zongye rope drawing
The color of the zongye rope used here is dark khaki. You can modify it according to your own aesthetics. You can find it directly on the Internet or use RGB to refine it. Finally, you can use hideturtle() to hide the arrow to make it more beautiful. When the arrow is turned At this time, it is best to raise the brush and close the fill. Penup() and end_fill() adjust the position and angle before turning it on, unless your program deliberately sets it this way. Of course, it is necessary to see the angle and position of the brush more intuitively. to adjust.

Summarize
It's a bit crude, but the blessing is sincere:
May your mood be full like a rice dumpling, your career and family closely connected like a rice dumpling leaf, and be happy! ! !
