Detailed explanation of the code to draw dynamic love and confess your love using Python

1. Preparation

1. Environment configuration

First, you need to make sure that the following libraries are installed in your Python environment:

pip install matplotlib numpy

If you are using Anaconda, you can install it through the following command:

conda install matplotlib numpy

2. Create a project file

In your working directory, create a new Python file, e.g.heart_animation.py, and start writing code in the file.

2. Code implementation

Below is a complete code example. We will create a dynamic love animation and add "I love you" confession text in the middle of love.

import numpy as np
import 
import  as plt
import  as animation
 
def heart_shape(t):
    """Creating the coordinates of the heart-shaped curve"""
    x = 16 * (t)**3
    y = 13 * (t) - 5 * (2*t) - 2 * (3*t) - (4*t)
    return x, y
 
def create_heart_plot():
    """Create a basic heart shape"""
    t = (0, 2 * , 1000)
    x, y = heart_shape(t)
    
    fig, ax = (figsize=(8, 8))
    (x, y, color='red')
    ax.set_xlim(-20, 20)
    ax.set_ylim(-20, 20)
    ('off')  # Close the axis    return fig, ax
 
def update(frame, ax):
    """Update function for animation"""
    ()  # Clear the current graph    
    # Re-draw the heart    t = (0, 2 * , 1000)
    x, y = heart_shape(t)
    (x, y, color='red')
    
    # Add confession text    (0, 0, f'I love you!  Xiaoya', fontsize=30, ha='center', va='center', color='white', fontweight='bold')
    
    # Add dynamic effects    (0, -5, f'The {frame + 1} Width', fontsize=20, ha='center', va='center', color='white', fontweight='bold')
    
    ax.set_title('Dynamic Love', fontsize=20, color='white')
    ax.set_xlim(-20, 20)
    ax.set_ylim(-20, 20)
    ('off')  # Close the axis 
def main():
    # Set fonts    [''] = 'SimHei'  # Use bold    ['axes.unicode_minus'] = False  # Handle negative sign display 
    fig, ax = create_heart_plot()
    
    # Create animation    ani = (fig, update, frames=100, fargs=(ax,), interval=100)
    
    # Show animation    ()
 
if __name__ == "__main__":
    main()

Detailed code explanation

Import library：
- numpyUsed for mathematical calculations, processing arrays and numerical values.
- Used to draw and display graphics.
- Used to create animation effects.
Heart-shaped function：
- heart_shape(t)Functions are based on parameterstCalculate the x and y coordinates of the heart shape. The heart-shaped formula used here is the classic polar coordinate equation, and this function returns the coordinates of the heart-shaped.
Basic graphic creation：
- create_heart_plot()Functions create the infrastructure of a heart-shaped figure, set the size and coordinate range of the figure, and close the coordinate axis.
Update animation functions：
- update(frame, ax)It is an update function for every frame in the animation. It clears the current figure, then repaints the heart shape, and adds the confession text.
- Dynamically added "xth" text allows the audience to feel dynamic changes in real time.
Main function：
- existmain()In the function, call the function that creates a heart chart and useCreate an animation.framesThe parameters define the number of frames of the animation.intervalControls the time interval between frames.

Running effect

After running the above code, you will see a dynamic red love heart with the text "I love you!" displayed in the center of your heart. At the same time, the current frame count will be displayed at the bottom, which makes the entire animation look more vivid and interesting.

3. Code expansion and optimization

To make our love animation more attractive, we can also perform the following extensions and optimizations:

1. Add gradient effect

We can change the color of the heart dynamically to make it look more layered in the animation. The following is the modified code snippet:

def update(frame, ax):
    """Update function for animation"""
    ()  # Clear the current graph    
    # Re-draw the heart    t = (0, 2 * , 1000)
    x, y = heart_shape(t)
 
    # Calculate color gradient    color = (1.0, 0.0, 0.0, (frame % 100) / 100.0)  # Red gradient    
    (x, y, color=color)
    
    # Add confession text    (0, 0, f'I love you!  Xiaoya', fontsize=30, ha='center', va='center', color='white', fontweight='bold')
    
    # Add dynamic effects    (0, -5, f'The {frame + 1} Width', fontsize=20, ha='center', va='center', color='white', fontweight='bold')
    
    ax.set_title('Dynamic Love', fontsize=20, color='white')
    ax.set_xlim(-20, 20)
    ax.set_ylim(-20, 20)
    ('off')  # Close the axis

In this way, the color of the heart shape will gradually change over time, increasing the visual dynamics.

2. Add background music

When confessing, pairing with moving music can increase the communication of emotions. Can use PythonpygameKuan is here to play background music. First install the library:

pip install pygame

Then load the music in the code:

import pygame
 
# Music Initialization()
('your_music_file.mp3')  # Replace with your music file path(-1)  # Loop play 
# Add music playback in main functiondef main():
    (-1)  # Play music loop    fig, ax = create_heart_plot()
    
    # Create animation    ani = (fig, update, frames=100, fargs=(ax,), interval=100)
    
    # Show animation    ()

3. Make text dynamically change

You can add different confession content to the confession text to make it dynamically change in the animation. You can use a list to store different confession sentences:

expressions = [
    "I love you! ❤️",
    "You are my only one! 💖",
    "Spend the rest of your life with you! 💞",
    "I wish to join hands with you! 💘"
]
 
def update(frame, ax):
    """Update function for animation"""
    ()  # Clear the current graph    
    # Re-draw the heart    t = (0, 2 * , 1000)
    x, y = heart_shape(t)
 
    # Calculate color gradient    color = (1.0, 0.0, 0.0, (frame % 100) / 100.0)  # Red gradient    
    (x, y, color=color)
    
    # Dynamically changing confession text    message = expressions[frame % len(expressions)]
    (0, 0, message, fontsize=30, ha='center', va='center', color='white', fontweight='bold')
    
    # Add dynamic effects    (0, -5, f'The {frame + 1} Width', fontsize=20, ha='center', va='center', color='white', fontweight='bold')
    
    ax.set_title('Dynamic Love', fontsize=20, color='white')
    ax.set_xlim(-20, 20)
    ax.set_ylim(-20, 20)
    ('off')  # Close the axis
