I am creating a simulation of a forest fire using a twodimensional array by programming. The language I'm using is python. I am using visual studio.
Place trees on the ground on the N × N square. A tree is growing with a probability of p (state: 1). No tree is growing with probability 1p (state: 0) Example: map1 [x] [y] = 1 → Feeling that a tree is growing.
Let 2 be the state of the burning tree and 3 be the state of the extinguished tree.
Set the initial value of map1 [x] [y] to 0 or 1, set some trees to 2 in the first step, and update the steps until the fire is completely extinguished. When (x, y) is 1, (x, y) becomes 2 if any one of the adjacent squares is in the state of 2, and becomes 3 in the next step. 2 spreads to only 1 square in 1 step.
Two or more squares of fire will spread in one step. As my policy, I created the code for each of the four corners, four sides, and the middle. I tried rewriting the fire spread step several times, but it still didn't work.
Can you tell me what's wrong?
Thank you.

What I tried
The value of the random number is fixed.
