英文

判斷大小寫時用ansi_raw, 字符下標遞增，改成：

import?sys

import?math

yuanshi=raw_input("please?input")

liebiao=list(yuanshi)

changdu=len(yuanshi)

value=0

while?value<26:

value=value+1

i=0

while?i<changdu:

ansi_raw=ord(liebiao[i])

ansi=ansi_raw+int(value)

if?ansi_raw>=65?and?ansi_raw<=90:

ansi=ansi_raw+value

if?ansi>90:

ansi=ansi-26

elif?ansi_raw>=97?and?ansi_raw<=122:

ansi=ansi_raw+value

if?ansi>122:

ansi=ansi-26

else:

ansi=ansi

print?chr(ansi),

i?+=?1

print?"?"

也可以這樣寫（不輸出原始字符串）：

yuanshi=raw_input("please?input:?")

la?=?ord('a')

ua?=?ord('A')

for?offset?in?xrange(1,?26):

for?c?in?yuanshi:

o?=?ord(c)

if?c.islower():

print?chr(la?+?(o?-?la?+?offset)%26),

elif?c.isupper():

print?chr(ua?+?(o?-?ua?+?offset)%26),

else:

print?c,

print
