Input

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

alphabet = 'abcdefghijklmnopqrstuvwxyz'
cipher = dict()
for num, letter in enumerate(alphabet, 1):
    cipher[ord(letter)] = str(num) + '-'
S = input('Input string: ').lower().split()
for word in S:
    print(word.translate(cipher)[:-1], end=' ')
