English: SIR model simulated in python, The 100x100 matrix is first randomly seeded. A value of 1 indicates a person is recovered, a value that is larger than 0.5 indicates a person is infected, and a value that is less than 1 indicates a person is susceptible. In this case, an infected person can spread the disease to the eight people around him, with people on the border as an exception. The outermost ring of points are not included as the simulation, and should be considered as irrelevant.--Andrew Luo
