Drawing a Semi-Circle with Python Turtle

Python Turtle is a popular and beginner-friendly way to learn programming through creating visual arts and animations. One of the basic shapes you can draw using Turtle is a semi-circle. Drawing a semi-circle involves understanding how to control the movement and turning of the turtle cursor.

Here’s a step-by-step guide on how to draw a semi-circle using Python Turtle:

1.‌Import the Turtle Module‌:
First, you need to import the Turtle module in Python. This can be done by writing import turtle at the beginning of your code.

2.‌Create a Turtle Object‌:
Next, create a turtle object that you can use to draw. For example, you can name it pen.

3.‌Set the Starting Position‌:
Use the penup() method to lift the pen, move to the starting position using the goto() method, and then use pendown() to start drawing.

4.‌Draw the Semi-Circle‌:
To draw a semi-circle, you can use the circle() method with the radius of the desired circle as its argument. Since you want a semi-circle, you need to specify an additional argument for the extent of the arc, which is 180 degrees for a semi-circle. This can be done by passing 180 as the second argument to the circle() method.

5.‌Hide the Turtle‌:
Once you’ve finished drawing, you might want to hide the turtle cursor using the hideturtle() method to make the final output look cleaner.

Here’s an example code snippet that demonstrates how to draw a semi-circle:

pythonCopy Code
import turtle

# Create a turtle object
pen = turtle.Turtle()

# Set the starting position
pen.penup()
pen.goto(0, -100)
pen.pendown()

# Draw a semi-circle
pen.circle(100, 180)

# Hide the turtle cursor
pen.hideturtle()

# Keep the window open
turtle.done()

This code will create a window where a semi-circle is drawn starting from the position (0, -100) with a radius of 100 units.

Drawing shapes like semi-circles with Python Turtle is a fun way to learn programming fundamentals such as loops, functions, and angles. It also helps develop an understanding of basic geometry concepts.
