将字符串s='ab34aa243dd78eww89' 处理为 '**34**243**78***89',然后对数字求和，结果为'**7**9**15***17'

result=‘‘
for i in s:
    if i.isalpha():
        result+=‘*‘
    else:
        result+=i

print(result)
i=0
temp=0
ss=‘‘

while i<len(result):
    if result[i].isdigit():

            ss+=str(temp)
        ss+=result[i]
        temp=0
    i+=1
ss+=str(temp)
print(ss)
