## Python Code of Monte Carlo Simulations

#### Here’s a simple example of a simulation in Python, estimating the value of pi:

```
import random
import math
def monte_carlo_simulation_pi(num_points):
points_inside_circle = 0
for _ in range(num_points):
x = random.uniform(-1, 1)
y = random.uniform(-1, 1)
distance_from_origin = math.sqrt(x**2 + y**2)
if distance_from_origin <= 1:
points_inside_circle += 1
pi_estimate = 4 * points_inside_circle / num_points
return pi_estimate
num_points = 1000000
pi_estimate = monte_carlo_simulation_pi(num_points)
print(f"Estimated value of pi using {num_points} points: {pi_estimate}")
```

#### This Python code demonstrates a Monte Carlo simulation to estimate the value of pi. The simulation generates random points within a square with side length 2, centered at the origin, and counts the number of points that fall inside a circle with radius 1, also centered at the origin. The estimated value of pi is calculated based on the ratio of the points inside the circle to the total number of points.
