Как нарисовать полукруг только в Python turtle
Как нарисовать полукруг (полукруг) только черепахой питона?
Я могу использовать только черепаху Python. Я пытался найти ресурсы, но мне не удалось найти тот, который использует только черепаху Python.

Для рисования полукруга в черепахе питона очень просто все, что вам нужно сделать, это
Для круга первая цифра — это радиус круга, а вторая — величина, которую вы хотите нарисовать для полукруга, вы можете использовать 180 градусов, как показано в приведенном выше коде, но вы можете сделать четверть круга, тогда если вы хотите соединить полукруг, просто поверните налево, затем вперед на радиус * 2
Вы также можете сделать это, просто используя круг. turtle.circle(radius, extent,steps) например.
Если вам также нужна линия под полукругом (например, луна), попробуйте это
Для полноты картины, способ создать полукруг с черепахой с помощью штамповки вместо рисования :
У него есть очевидные недостатки, но иногда это именно то, что вам нужно.
См. справочник по черепахе Python в круге. Например, для полукруга радиусом 100 это будет:

- Как вы пришли к диаметру 118? Поскольку черепаха каждый раз движется вперед на 1, я бы ожидал, что диаметр будет равен 360 окружности / math.pi, что ближе к 115, что нормально работает — 118 отклонений (если вы спрячете саму черепаху)
- Понятия не имею, @cdlane. Это было 2 года назад. Отредактирую на 115.

turtle — Turtle graphics¶
Turtle graphics is a popular way for introducing programming to kids. It was part of the original Logo programming language developed by Wally Feurzeig, Seymour Papert and Cynthia Solomon in 1967.
Imagine a robotic turtle starting at (0, 0) in the x-y plane. After an import turtle , give it the command turtle.forward(15) , and it moves (on-screen!) 15 pixels in the direction it is facing, drawing a line as it moves. Give it the command turtle.right(25) , and it rotates in-place 25 degrees clockwise.
Turtle can draw intricate shapes using programs that repeat simple moves.
By combining together these and similar commands, intricate shapes and pictures can easily be drawn.
The turtle module is an extended reimplementation of the same-named module from the Python standard distribution up to version Python 2.5.
It tries to keep the merits of the old turtle module and to be (nearly) 100% compatible with it. This means in the first place to enable the learning programmer to use all the commands, classes and methods interactively when using the module from within IDLE run with the -n switch.
The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses tkinter for the underlying graphics, it needs a version of Python installed with Tk support.
The object-oriented interface uses essentially two+two classes:
The TurtleScreen class defines graphics windows as a playground for the drawing turtles. Its constructor needs a tkinter.Canvas or a ScrolledCanvas as argument. It should be used when turtle is used as part of some application.
The function Screen() returns a singleton object of a TurtleScreen subclass. This function should be used when turtle is used as a standalone tool for doing graphics. As a singleton object, inheriting from its class is not possible.
All methods of TurtleScreen/Screen also exist as functions, i.e. as part of the procedure-oriented interface.
RawTurtle (alias: RawPen ) defines Turtle objects which draw on a TurtleScreen . Its constructor needs a Canvas, ScrolledCanvas or TurtleScreen as argument, so the RawTurtle objects know where to draw.
Derived from RawTurtle is the subclass Turtle (alias: Pen ), which draws on “the” Screen instance which is automatically created, if not already present.
All methods of RawTurtle/Turtle also exist as functions, i.e. part of the procedure-oriented interface.
The procedural interface provides functions which are derived from the methods of the classes Screen and Turtle . They have the same names as the corresponding methods. A screen object is automatically created whenever a function derived from a Screen method is called. An (unnamed) turtle object is automatically created whenever any of the functions derived from a Turtle method is called.
To use multiple turtles on a screen one has to use the object-oriented interface.
In the following documentation the argument list for functions is given. Methods, of course, have the additional first argument self which is omitted here.

In this Python Turtle tutorial, we will learn How to create an oval shape in Python Turtle and we will also cover different examples related to Turtle oval. And, we will cover these topics.

Python turtle oval
In this section, we will learn about how to create an oval with the help of a turtle in a python turtle.
Oval is a closed curve rounded figure. It looks like an egg. It has no corner or straight line we can say it just look like a circle but not a perfect circle. Here we draw an oval with help of a turtle. The turtle acts as a pen and draws the oval shape on the drawing board and there is a screen that acts as a drawing board.
Code:
In the following code, we will import the turtle library from turtle import *, import turtle as tur.
- tur.circle(rad,90) is used to draw an oval shape.
- tur.seth(-45) is used to tilt the shape to negative 45.
- drawoval(100) is used to call the draw method.
Output:
After running the above code we will get the following output in which we can see an oval shape is drawn on the screen it looks like an egg or ellipse.
Python turtle oval visuals
In this section, we will learn about how to draw oval visual arts with the help of a turtle in a python turtle.
Visual is an art that is used for drawing pictures and creating videos it also focuses on creating pieces of work. Here the oval visuals are drawn with the help of a turtle and drawing a beautiful shape that can attract people’s eyes and this oval shape visual is drawn on the drawing board here screen works as a drawing board.
Code:
In the following code, we will import the turtle library from turtle import *, import the turtle package import turtle as tur. The turtle() method is used to make objects.
- ws.setup(500,500) is used for setting the screen size.
- ws.bgcolor(‘black’) is used for giving the color to the pen.
- col=[‘cyan’,’blue’,’pink’,’purple’,’yellow’,’green’] is used to give the color to the pen for drawing the shape with the help of different colors.
- tur.speed(100) is used to give the speed to the turtle.
- drawoval(80) is used to call the function for drawing an oval shape.
- value+=10 is used for changing the orientation.
- tur.hideturtle() is used to hide the turtle from the screen.
Output:
After running the above code we get the following output in which we can see a beautiful oval visual art is drawn on the screen with help of a turtle.
