String - Vowels Position Sum

 Coding Problem Keys 

 String - Vowels Position Sum 

 Problem Statement 

The string S is accepted as the input. The program must print the sum of the positions of the vowels in S. If the string does not contain any vowels then print -1.

 Boundary Condition(s) 

2 <= Length of the string S <= 100

 Input Format 

The first line contains the value of String S.

 Output Format 

The first line contains the sum of the positions of the vowels in S.

 Example Input/Output 1 

 Input 

nose

 Output 

6

 Explanation 

The vowels in the string are o and e. The position of o is 2 and the position of e is 4. The sum of the positions = 2 + 4 = 6.

Hence the output is 6.

 Example Input/Output 2 

 Input 

xyz

 Output 

-1

 Explanation 

There are no vowels in the given string S. Hence the output is -1.

 Max Execution Time Limit: 5000 millisecs 

 Solution 

 Programming Language: Python 3 Language 

l=list(input().strip())
l.insert(0,"");s=0;count=0
vowels=list("aeiouAEIOU")
for i in range(len(l)):
    if(l[i] in vowels):
        s+=i;count+=1
if(count==0):
    print("-1")
    pass
else:
    print(s)
