用python计算圆周率PI

1.要求能算到小数点后面越多越好（5分）????????????????????????????????????????????????????????????????????????????????????????????????

2.并用进度条提示算的进度，，能给出多种进度条越好（5分）????????????????????????????????????????????????????????????????????????????????????????????????

3.要求给出算圆周率Pi具体公式或者算法说明

1 pi = 0
2 N = 100
3 for k in range(N):
4     pi += 1/pow(16,k) * (4/(8 * k + 1) - 2/(8 * k + 4) - 1/(8 * k + 5) - 1/(8 * k + 6))
5     print("圆周率值是：{}".format(pi))
6     from tqdm import trange
7     import time
8     for i in trange(100):
9         time.sleep(0.1）
