我试图从生成的字谜列表中找到回文。这里的转折是我最初的输入是一个回文列表。我基本上试图自动寻找一个回文的回文,这是一个回文的字谜(不是家庭作业,只是一个英国书呆子)。
输入的原始回文将来自'pals.txt',其中回文符号是行分隔的,并且删除了空格和非数字字符。我使用英国 - 英语词典文件'dictionary.txt'来生成字谜。
我很感激任何输入,因为我仍然是一个初学程序员。谢谢!
def isPalindrome(s):
return s.lower() == s[::-1].lower()
def anagramchk(word,chkword):
for letter in word:
if letter in chkword:
chkword = chkword.replace(letter, '', 1)
else:
return 0
return 1
f0 = open('pals.txt', 'r')
f1 = open('dictionary.txt', 'r')
for line in f0:
wordin = line
for line in f1:
line = line.strip()
if len(line) >= 4:
if anagramchk(line, wordin):
if isPalindrome(line):
print line
f0.close()
f1.close()
答案 0 :(得分:2)
import collections
def isPalindrome(s):
return s.lower() == s[::-1].lower()
def anagramchk(word,chkword):
return sorted(word.lower()) == sorted(chkword.lower())
def allAnagrams(dictfilepath):
answer = collections.defaultdict(list)
with open(dictfilepath) as dictfile:
for line in dictfile:
word = line.strip().lower()
answer[''.join(sorted(word))].append(word)
return answer
def fetchAllAnagrams(wordin, anagrams):
return anagrams[''.join(sorted(wordin.lower()))]
def main(dictfilepath, palsfilepath):
anagrams = allAnagrams(dictfilepath)
with open(palsfilepath) as palfile:
for line in palfile:
word = line.strip().lower()
if isPalindrome(word):
for anagram in anagrams[''.join(sorted(word))]:
if isPalindrome(anagram):
print "%s is an anagram of %s" %(anagram, word)
假设您的文件路径为'path/to/dictfile'
和'path/to/palsfile'
,那么您可以按如下方式调用main
:
main('path/to/dictfile', 'path/to/palsfile')
希望这有帮助
