Sim #1 updates 2 variables by a random amount at each iteration (runs for 100 iterations) 

import random

# Define the number of iterations
num_iterations = 100

# Set the initial values of the variables
value_1 = 0
value_2 = 0

# Define the update function
def update_values():
  global value_1
  global value_2
  value_1 += random.randint(-1, 1)
  value_2 += random.randint(-1, 1)

# Run the simulation for the specified number of iterations
for i in range(num_iterations):
  update_values()
  print(f"Iteration {i}: value_1 = {value_1}, value_2 = {value_2}")

Sim #2 an object falling under the influence of gravity 

import matplotlib.pyplot as plt

# Define the initial conditions
x = 0
y = 0
vx = 0
vy = 0
g = 9.8

# Set the time step and number of iterations
dt = 0.1
num_iterations = 100

# Define the update function
def update_position():
  global x, y, vx, vy
  x += vx * dt
  y += vy * dt
  vy -= g * dt

# Run the simulation for the specified number of iterations
for i in range(num_iterations):
  update_position()

# Plot the results
plt.plot(x, y)
