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. abcdefghij12345678910 klmnopqr1112131415161718 stuvwxyz1920212223242526Input 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.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():
 N = input("Enter a string: ")
 O=""
 for letter in N:
    num=getNum(letter)
    if(num!=-1):
     O+=str(num)+"-"
    else:
     O+=letter
 print(O[:-1])
def getNum(letter):
 characters = "abcdefghijklmnopqrstuvwxyz"
 for i in range(0,len(characters)):
     if letter.islower() and letter==characters[i]:
       return i+1
     if letter.isupper() and letter==characters[i].upper():
      return i+1
 return -1
main()
