Question

python编写程序求级数-1+1/2-1/3+1/4-……1/99+1/100的值

Answer 1

def calculate_series():
    series_sum = 0
    sign = -1

    for i in range(1, 101):
        sign *= -1
        term = sign / i
        series_sum += term

    return series_sum

result = calculate_series()
print("级数的值为:", result)

最后级数的值差不多是: -0.688172179310195
