A1ex-13
can be schematically represented by the set of following functions:
def CaesarCipherChar(c, k):
a1 = 'ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ'
a2 = 'abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz'
if c.isalpha()==True:
if 'A' <= c <= 'Z':
return(a1[(a1.index(c) + k) % len(a1)])
if 'a' <= c <= 'z':
return(a2[(a2.index(c) + k) % len(a2)])
else:
return (c)
return c
def CaesarCipher(s,K):
k = int(K)
word = ''
for c in s:
word += CaesarCipherChar(c,k)
return word
Indication:
S = input('Enter word: ')
K = input('Enter number (1<= k <=26): ')
print(CaesarCipher(S,K))
