代码如下:
import math import time scale=14 s,m,=1,2 print("执行开始".center(scale//2, "-")) start = time.perf_counter() for i in range(scale+1): s=math.sqrt((1-math.sqrt(1-pow(s,2)))/2) m=m*2 a = '*' * i b = '.' * (scale - i) c = (i/scale)*100 dur = time.perf_counter() - start print(" {:^3.0f}%[{}->{}]{:.2f}s".format(c,a,b,dur)) time.sleep(0.1) Pi=s*m print("Pi值是{}".format(Pi)) print(" "+"执行结束".center(scale//2,'-'))
运行结果如下:
如果还想计算更加精确的数值,还可以通过修改上面相应的数值。
