Python实现圆周率的计算代码实现

 

import random
import time
N = 10000
n = 0
start = time.time()
for i in range(N):x = random.random()y = random.random()if ((x-0.5)**2 + (y-0.5)**2)<0.25:n=n+1
end = time.time()
cost = end - start
print('pi = ' + str(n/N*4.0) + "耗时：" + str(cost) + "秒")

 

Python实现圆周率的计算，次数越多越精确
