Python 圆周率撒点计算

Python 圆周率撒点计算

浅浅的尝试一下

from random import random
from time import perf_counter
import datetime
import time

l=0

while True:

	a=1000*1000
	b=0.0
	c=perf_counter()

	for i in range(1,a+1):
    	x,y=random(),random()
    	d=pow(x **2 + y **2,0.5)
    	if d<=1.0:
        	b=b+1
	e=4*(b/a)

	print(e)
	j=('--->{:.5f}s'.format(perf_counter()-c))

	#time.sleep(1)



	if l<=100 or e==3.141592:
    	l=l+1
    
    	print('--->',l,'<---')
    	if l>100 and e==3.141592:

        	print('write','5s')

        	time.sleep(5)

        	now=datetime.datetime.now()

        	p=(e,'---',l,'次')
        	file=open(r'D:\库\日志.txt',"a")
        	file.write(p)
        	file.close()

        	file=open(r'D:\库\日志.txt',"a")
        	file.write(now)
        	file.close()

        	break

效果不错

勉强能用
