Valentine Day Project using Python Turtle With Source Code

Introduction :

Valentine’s Day, a day of love and affection, is just around the corner. Why not celebrate it in a unique way this year? Let’s create a beautiful animation of hearts using Python’s Turtle module. This project is not only fun but also a great way to learn and understand Python programming.

Required Python Modules :

This project requires two Python modules: turtle and math. The turtle module is a part of Python’s standard library and is used for creating graphics. The math module provides mathematical functions and is used in this project to calculate the shape of the heart.

Code Explanation :

Let’s break down the code into smaller parts for better understanding:

Importing Modules: We start by importing the necessary modules. turtle for graphics and math for mathematical functions.
Setting up the Environment: We create a turtle object t and a screen wn. We set the turtle’s shape to “turtle”, the background color to “lavender blush”, and the turtle’s speed to 4.
Color Function: This function sets the pen color based on the iteration number. We have a list of colors, and we choose the color by taking the remainder of the iteration number divided by the length of the color list.
At Function: This function moves the turtle to a specific location on the screen without drawing anything.
Heart Function: This function draws a heart. It takes two parameters: size and shape. The size determines the size of the heart, and the shape determines the shape of the heart. We use the sin function from the math module and some geometry to calculate the radius of the circles that form the heart.
Hearts Function: This function draws a series of hearts. For each iteration, it changes the color, moves the turtle down, and draws a heart with increasing size.
Displaying the Message: We move the turtle to specific locations and use the write method to display a message.
