Question

Secret Message - 2

Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.

Note: You need to replace both uppercase and lowercase characters. You can ignore replacing all characters that are not letters.

Input

The input will be a string in the single line containing spaces and letters.

Output

The output should be a single line containing the secret message. All characters in the output should be in lower case.

Explanation

For example, if the given input is "python", "p" should replaced with "16", similarly "y" with "25","t" with "20","h" with "8","o" with "15","n" with "14". So the output should be "16-25-20-8-15-14".

Answer 1

def main():
    s1 = input("Enter string: ")
    s2=""
    for alphabet in s1:
        num=getNum(alphabet)
        if(num!=-1):
            s2+=str(num)+"-"
        else:
            s2+=alphabet




    print(s2[:-1])
def getNum(alphabet):
    letters = "abcdefghijklmnopqrstuvwxyz"
    for i in range(0,len(letters)):
        if alphabet.islower() and alphabet==letters[i]:
            return i+1
        if alphabet.isupper() and alphabet==letters[i].upper():
            return i+1
    return -1
