A beautiful Python animation that celebrates Valentine's Day with animated hearts using the Turtle graphics module. Perfect for beginners learning Python or anyone wanting to create a romantic coding project!

Watch the hearts come to life with beautiful colors and animation!

• Animated Heart Graphics - Multiple hearts drawn with increasing sizes for a 3D depth effect
• Colorful Display - Cycles through romantic colors (red, pink, hotpink, deeppink)
• Mathematical Precision - Uses trigonometric functions to create perfect heart curves
• Customizable Message - Displays your own Valentine's Day greeting
• Smooth Animation - Controlled turtle speed for pleasant visual effects
• No Dependencies - Uses only Python standard library

This project requires Python 3.6+ and uses only standard library modules:

import turtle  # For graphics and animations
import math    # For mathematical calculations

✅ No pip install needed! Everything is included with Python.

# Clone this repository
git clone https://github.com/yourusername/valentine-heart-animation.git

# Navigate to the project directory
cd valentine-heart-animation

# Run the script
python valentine_hearts.py

The animation window will open automatically. Press the window to close when finished.

The project consists of several key components:

t = turtle.Turtle()          # Create turtle object
wn = turtle.Screen()          # Create screen
wn.bgcolor("lavender blush")  # Set background
t.speed(4)                    # Set animation speed

def color(i):
    colors = ['red', 'pink', 'hotpink', 'deeppink']
    t.pencolor(colors[i % len(colors)])

Cycles through 4 romantic colors for each heart.

def heart(size, shape):
    # Uses sin() function and geometry to calculate heart curves
    # Draws using circles and precise angles for symmetry

The heart shape is created using:

• Trigonometric functions (sine) for smooth curves
• Circle geometry for rounded parts
• Parametric equations for perfect symmetry

def hearts(num):
    for i in range(num):
        color(i)              # Change color
        t.sety(t.ycor() - 10) # Move down
        heart(10 + i * 5, 1)  # Draw larger heart

Draws multiple hearts with increasing sizes.

t.write("Happy Valentine's Day!", font=("Arial", 24, "bold"))

Examples of different color schemes and sizes

# In the color() function, modify the colors list:
colors = ['purple', 'violet', 'magenta', 'orchid']  # Purple theme
colors = ['blue', 'cyan', 'lightblue', 'skyblue']   # Blue theme
colors = ['green', 'lime', 'lightgreen', 'spring green']  # Green theme

# In the hearts() function:
heart(10 + i * 5, 1)   # Default size
heart(5 + i * 3, 1)    # Smaller hearts
heart(20 + i * 10, 1)  # Larger hearts

wn.bgcolor("lavender blush")  # Default - soft pink
wn.bgcolor("black")            # Dark romantic
wn.bgcolor("light pink")       # Bright pink
wn.bgcolor("misty rose")       # Soft rose
wn.bgcolor("alice blue")       # Light blue

t.speed(1)   # Slowest - watch every detail
t.speed(4)   # Default - smooth animation
t.speed(10)  # Fastest - quick rendering
t.speed(0)   # Instant - no animation

# Modify the text and positioning:
at(-200, 100)
t.write("I Love You!", font=("Arial", 28, "bold"))

at(-250, 50)
t.write("Be My Valentine?", font=("Courier", 20, "italic"))

Problem: Animation window doesn't appear
Solution: Make sure Python is installed correctly and turtle module is available

Problem: Hearts look distorted
Solution: Try adjusting the screen resolution or turtle speed

Problem: Colors don't show properly
Solution: Check your terminal supports colors, or try different color names

Problem: Program closes immediately
Solution: Add turtle.done() at the end of the script
