Ceasar Cipherのラップアラウンド

Question

私はCeasar暗号をラップアラウンドさせようとしています。残念ながら、私はそれを実装する方法についてはわかりません。それが現在であるとしてここに私のコードです：

maximum_character = unciphered_text[0] 
maximum_count = unciphered_text.count(unciphered_text[0]) 
for char in unciphered_text: 
    if char is not " ": 
     if unciphered_text.count(char) > maximum_count: 
      maximum_character = char 

print("The most frequent character used is: ", maximum_character) 

ASCII_maximum = maximum_character.lower() 
ASCII_number = ord(ASCII_maximum) 
print(ASCII_number) 

shift_distance = ord('e')-ASCII_number 
print("The shift distance is: ", shift_distance) 

def caesar_cipher(unciphered_text, shift_distance): 
    ciphered_text = "" 
    for char in unciphered_text: 
     if char.isalpha(): 
      cipher_process = ord(char)+shift_distance 
      if cipher_process > ord('z'): 
      cipher_process -= 26 
      post_translation = chr(cipher_process) 
      ciphered_text += post_translation 
    return ciphered_text 

answer = caesar_cipher(unciphered_text, shift_distance) 
print(answer) 

は私のコードは、それがプロセス内のスペースや適切な句読点を削除して終わる読みやすい何かに入力を翻訳することができますが。

Answer 1

あなたはあなたの答えにそれらを転写する必要があります。

for char in unciphered_text: 
    if char.isalpha(): 
     cipher_process = ord(char.upper()) + shift_distance 
     if cipher_process > ord('Z'): 
      cipher_process -= 26 
     if cipher_process < ord('A'): # Deal with underflow 
      cipher_process += 26 
     post_translation = chr(cipher_process) 
     ciphered_text += post_translation 
    else: # skip, but include non-alphabetic characters 
     ciphered_text += char 

はまた、あなたが大文字に変換する文字を.upper()、およびA下の文字のアンダーフローに対処する必要があります。

サンプル出力（事実の後に追加リターン）：

COWARDS DIE MANY TIMES BEFORE THEIR DEATHS; THE VALIANT NEVER TASTE 
OF DEATH BUT ONCE. OF ALL THE WONDERS THAT I YET HAVE HEARD, IT SEEMS 
TO ME MOST STRANGE THAT MEN SHOULD FEAR; SEEING THAT DEATH, A NECESSARY 
END, WILL COME WHEN IT WILL COME
