Python字符串轉換器;如何在python中轉換字符串

Question

假設有一個字符串（「Hello！Python is a great language！」），那麼我將如何轉換Hello！進入hijkefghlmnolmnoopqr！如果h = hijk e = efgh l = lmno o = opqrs等字符串的其餘部分？

Answer 1

LETTERS = "abcdefghijklmnopqrstuvwxyzabc" 

def translate_char(ch): 
    i = LETTERS.find(ch.lower()) 
    if i == -1: 
     return ch 
    else: 
     return LETTERS[i:i + 4] 

def translate_string(s): 
    return "".join(translate_char(ch) for ch in s) 

print(translate_string("Hello!")) # => hijkefghlmnolmnoopqr! 

Answer 2

subs = {} 
alpha = 'abcdefghijklmnopqrstuvwxyzabc' 
for i in range(26): 
    subs[alpha[i]] = alpha[i:i+4] 
s = "Hello! Python is a great language!" 
s = ''.join(subs.get(c, c) for c in s.lower())
