您可以使用以下 Python 代码来求解 1-1/3 1/5 的值:
n = int(input('输入项数 n:'))
s = 0
for i in range(1, n+1):
if i % 2 == 1:
s += 1 / (2*i - 1)
else:
s -= 1 / (2*i - 1)
print('%.2f' % s)
在这段代码中,我们使用一个 for 循环来计算表达式的每一项,根据项的奇偶性来决定加法或减法运算。最后,我们使用格式化字符串的方式保留两位小数并打印出结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
