用python计算圆周率

import math
import time
scale=14 #scale的值越大，π的值越精确，但运算时间会加长
s,m,=1,2
total,s,n,t=0.0,1,1.0,1.0
print("执行开始".center(scale//2, "-"))
start = time.perf_counter()
for i in range(scale+1):
total+=t
n+=2
s=-s
t=s/n
k=total*4
a = ‘*‘ * i
b = ‘.‘ * (scale - i)
c = (i/scale)*100
dur = time.perf_counter() - start
print("\r{:^3.0f}%[{}->{}]{:.2f}s".format(c,a,b,dur))
time.sleep(0.1)
Pi=k
print("Pi值是{}".format(Pi))
print("\n"+"执行结束".center(scale//2,‘-‘))
