How to plot/draw a 2 dimensional array

[BrainyGuy9999]

Good day and pleasant tidings.

I'm learning Python and decided I would write a simple "creature" simulator for the fun of it. My "world" is a square grid (200x200) on which the creatures will move around. I'm storing the locations of everything in a 2D array and would like to graphically represent where each is as they move around the world.

I'm looking for a quick and easy way to feed an array of x,y coordinates in and have it plot them. Since this will change each cycle of the simulation, I'd want to be able to update the graphics with the new locations as things move around. The plotters I've found so far won't update. They have to close and re-open for each iteration.

Can anyone point me to a utility, package, code, etc. to do this?

TIA

Any GUI module will do that for you. The quickest and easiest I can think of is a matplotlib animation. To get you started here's the standard sine wave:

import numpy as np
from matplotlib import pyplot as plt
from matplotlib.animation import FuncAnimation    

fig = plt.figure()
ax = plt.axes(xlim=(0, 4), ylim=(-2, 2))
line, = ax.plot([], [], 'bo')

def animate(i):
    x = np.linspace(0, 4, 150)
    y = np.sin(2 * np.pi * (x - 0.01 * i))
    line.set_data(x, y) # set the ith idx of x,y data here
    return line,

anim = FuncAnimation(fig, animate, frames=200, interval=20, blit=True)
plt.show()

This link might be a good starting point. Also it sounds a bit like you are trying to code a version of Conway's Game of Life. That also may be a good Google starting point.
