计算π

根据莱布尼兹公式，可以用以下级数的收敛值等于π：

π=4/1-4/3+4/5-4/7+4/9-4/11...

def calculate_pi(n_terms: int) -> float:
    numerator: float = 4.0
    denominator: float = 1.0
    operation: float = 1.0
    pi: float = 0.0

    for _ in range(n_terms):
        pi += operation * (numerator / denominator)
        denominator += 2.0
        operation *= -1.0
    return pi


if __name__ == '__main__':
    print(calculate_pi(1000000))
