特殊a串数列求和python

特殊a串数列求和可以使用以下Python代码实现：

a, n = input().split()
n = int(n)
s = 0

for i in range(1, n + 1):
    s += int(a * i)

print("s = %d" % s)

或者可以使用如下的方法：

a, n = input().split()
n = int(n)
s = 0

for i in range(1, n + 1):
    m = int(a) * pow(10, i - 1)
    s += m

print("s = {0}".format(s))

以上两种方法都是通过循环计算每个a串的值，然后将其累加到结果s中。最后输出s的值作为结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
