input输入的字符串，要变成数字，要转换一下使用就可以。

如果还没学到正则表达式，就用isdigit（）方法和join（）方法，写个循环洗一下字符串

        if i.isnumeric(): #如果是数字就提取出来
            n += i
    return int(n) # 转换成int返回


n1 = intinstr(input())
n2 = intinstr(input())

print("%d" % (n1 + n2))# 输出结果

楼主，看下是不是这样的

可以考虑findall()函数配合正则表达式，re.findall('\d',字符串)，然后再拼接

s1=input()

n1=""
n2=""
for i in s1:
    if 57>=ord(i)>=48:
        n1+=(str)(i)
for i in s2:
    if 57>=ord(i)>=48:
        n2+=(str)(i)
print((int)(n1)-(int)(n2))

俺也是刚学{:1_908:}{:1_926:} 之前判断把'0'漏掉了
