Python实现圆周率的计算代码实现

 

import random
import time
import math

N = 1000000
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
calpi = n/N*4.0
deviation = math.pi - calpi
print('pi = ' + str(calpi))
print("误差：" + str(deviation))
print("耗时：" + str(cost) + "秒")

 

　　

 

Python实现圆周率的计算，次数越多越精确
