python 感染病毒

隨著全球新冠疫情的爆發,病毒再次成為人類生活中的焦點。而在計算機世界中,病毒也是不容忽視的存在。Python作為一門廣泛應用于計算機領域的編程語言,不僅可以幫助人們更好地理解和控制病毒,還可以利用其靈活性來模擬病毒的傳播過程,進行病毒預測和研究。

#模擬病毒傳播過程的Python代碼示例:
import numpy as np
import matplotlib.pyplot as plt
population = 1000     # 總人數
infected_num = 10     # 初始感染人數
infect_prob = 0.3     # 感染率
recovery_rate = 0.1   # 治愈率
def simulation(population, infected_num, infect_prob, recovery_rate):
healthy_num = population - infected_num
num_inf_statis = [infected_num]
num_hea_statis = [healthy_num]
num_healing_statis = [0]
num_dead_statis = [0]
while infected_num >0:
infect_people_num = np.random.binomial(healthy_num, infect_prob)
infect_people_num = min(infect_people_num, infected_num)
recover_people_num = np.random.binomial(infected_num, recovery_rate)
infected_num -= recover_people_num
healthy_num -= infect_people_num
num_inf_statis.append(infected_num)
num_hea_statis.append(healthy_num)
num_healing_statis.append(min(infected_num + recover_people_num, population))
num_dead_statis.append(max(infection_num - recover_people_num - healthy_num, 0))
return num_inf_statis, num_hea_statis, num_healing_statis, num_dead_statis
num_inf_statis, num_hea_statis, num_healing_statis, num_dead_statis = simulation(population, infected_num, infect_prob, recovery_rate)
plt.title('Simulation of virus spread')
plt.plot(num_inf_statis, label='infected')
plt.plot(num_hea_statis, label='healthy')
plt.plot(num_healing_statis, label='healing')
plt.plot(num_dead_statis, label='dead')
plt.xlabel('day')
plt.ylabel('population')
plt.legend()
plt.show()

以上示例代碼使用了numpy和matplotlib兩個Python庫模擬病毒的傳播過程,通過統計每日感染人數、治愈人數、死亡人數等,可以得出病毒傳播的動態變化。這種模擬病毒的方法可以幫助人們更好地了解病毒傳播的規律和反應,從而更好地控制和預測病毒的傳播情況。
