create an animation in python

To create an animation in Python, you can use the animation module of the matplotlib library. First, you need to create a figure, subplot, and a line plot. Here's an example code that creates a simple animation where the y-coordinate of the line plot is incremented by a random value in every frame:


main.py
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

# create a figure and a subplot
fig, ax = plt.subplots()

# create a line plot
line, = ax.plot([], [])

# set x and y limits of the plot
ax.set_xlim(0, 10)
ax.set_ylim(0, 10)

# function to generate data for the line plot
def data_gen():
    while True:
        yield np.random.rand(2)

# function to update the line plot
def update(data):
    x, y = data
    line.set_data(np.append(line.get_xdata(), x),
                  np.append(line.get_ydata(), y))
    return line,

# create an animation object
ani = animation.FuncAnimation(fig, update, data_gen, blit=True)

# show the animation
plt.show()

This code generates a random (x, y) value pair in the data_gen() function and appends it to the existing line plot in the update() function. The FuncAnimation() function creates an animation object and the plt.show() function displays the animation.
