What will be covered in this Blog:
What is Turtle?
Turtle is a pre-installed Python library. It that enables users to create pictures and shapes by providing them with a virtual canvas. The onscreen pen that you use for drawing is called as turtle.
The turtle has three attributes: a location, an orientation (or direction), and a pen.
Moving the Turtle Head
The turtle can move in four directions:
- Forward
- Backward
- Left
- Right
If you wish to know more about it, you can refer to Turtle Documentation. Use this link to navigate to the documentation.
Now that you are aware of Turtle basics, we can move forward to the coding section.
Time to code!
You can find all the code at my GitHub Repository. Drop a star if you find it useful.
In order to access the Python library, you need to import it into your Python environment, use the following command to import turtle it in your python script.
Now let’s define some properties,
- Let’s set the speed as 3 using speed method, that means the heart will not just appear on the screen, the drawing will have some animation.
- If you wish to change the background color, you can use the bgcolor method, by default it is white.
- You can adjust the pen’s thickness using pensize method, it will be slightly bold.
Now let’s define a function to define the curve, I am calling it as myfunc .
I will define a loop here for the first curve, we will set the direction right and move forward. Now let’s set the turtle color using the color method
- the first parameter will be the border color, the pen color, which we are passing as black
- the second parameter, red is the color used to fill inside our heart.
And once we have set the color, we can begin the fill using begin_fill method.
we call left and forward and finally call our function to get the first curve. It will look something like this.
Draw A Heart Using Python Turtle With Code
Looking for a tutorial on how to draw a heart using python then you are at the right place, today in this tutorial I will show you how to draw a heart using python turtle so follow this tutorial till the end.
Drawing a heart in python is a little difficult but you don’t have to worry about anything. I will show you how to draw and provide you with the source code of this program.
Want to propose boyfriend/girlfriend then you can use this program: I love you python program. Disclaimer use it only on programmers.
Python Code To Draw A Heart
Above is the python program to draw a heart. Now to run this program you need to have python installed on your computer, If you don’t have then follow this guide: Install and setup python on your computer.
To run this python program, follow the below steps:
- Create a new folder for this python project.
- Open it in a code editor of your choice.
- Create a python file with an ending .py extension.
- Copy the above code and paste it in your file.
Now you have the code, but there is one last thing you need to do as I have said I have used the turtle library for this program so you might need to install it if you get any errors like turtle module not found.
Turtle comes pre-installed with python setup, but if you get any errors you can reinstall it using the below command.
So now you have everything setup and you are ready to run the program, so to run this program open a command prompt at your program folder location and paste the below command.
The above command will run the program and it will open a new window and it will start drawing a heart and below is the finished drawing of a heart using python.
As you can see, we successfully drew a heart using python turtle. I hope you were able to run this program successfully.
Don’t want to create all the files and folders then you can run this program now using this online python compiler it is fast and easy.

You can see here, how can you plot a 3D hearth.
The author of the article have put together the implicit function plotting can be found here and the implicit function of the hearth, and got the code below:
I have changed the python to python3 in the first row. If you use Python 2 you need to set it back.

Tutorial: How to Draw a Simple Heart Shape with Python and Turtle
Simple Heart Shape with 4 Segments
The figure above shows, we can draw a simple heart shape with 4 segments: 2 lines and 2 arcs. We can continuously draw these 4 segments without lifting up the pen.
We start from the bottom tip of the heart. The heading for the blue line is 45 degrees. The second segment is 225 degree arc. After initial 45 degree heading and 225 degree turn, the heading of the turtle will be a 45+225=270 degrees, which is facing down perfectly. The rest of the two segments are symmetric to the first two. All we need to do is just turn the Turtle by 180 degrees before drawing the 3rd segment.
The next step is to figure out the ratio of blue segment and the radius of the arc. In the figure above, a triangle formed by two black lines and the blue line is a right triangle. The angle between two black lines is (360-225)/2 = 67.5 degrees, where 225 is the degree of the arc. Therefore, the ratio of blue line segment and the radius equals to tangent(67.5).
Here is the code:
You can easily draw a filled heart by calling begin_fill() and end_fill() functions:
