AByteofPython之回文

#設(shè)置需要過慮的標(biāo)點(diǎn)符號
forbidden = (".", "?", "!", ":", ";", "-", "—", "()", "[]", "...", "'", '""', "/", ",", " ")
#獲取一個(gè)字符串，書中要求確認(rèn)"Rise to vote, sir."是回文
text = input("請輸入：")
#將字符串倒過來
def reverse(text):
str_tmp = []
str = ""
for i in range(0,len(text)):
if text[i] in forbidden:
continue
else:
str_tmp.append(text[i].lower())#方便比較，將字母轉(zhuǎn)成小寫字母
return str.join(str_tmp)[::-1]
#做是否是回文檢測
