Answer to Question #219097 in Python for SSK

Question

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.

The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).Output

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

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():
    #Read string
    inputString = input("Enter string: ")
    outputString=""
    for letter in inputString:
        number=getNumber(letter)
        if(number!=-1):
            outputString+=str(number)+"-"
        else:
            outputString+=letter




    print(outputString)
#This function convert letter to number
def getNumber(letter):
    alphabet = "abcdefghijklmnopqrstuvwxyz"
    for i in range(0,len(alphabet)):
        if letter.islower() and letter==alphabet[i]:
            return i+1
        if letter.isupper() and letter==alphabet[i].upper():
            return i+1
    return -1
