试图让这个拼写检查器我在网上遇到工作，但没有运气。任何帮助，将不胜感激。来自http://norvig.com/spell-correct.html的原始代码

import re, collections, codecs

def words(text): return re.findall('[a-z]+', text.lower()) 

def train(features):
    model = collections.defaultdict(lambda: 1)
    for f in features:
        model[f] += 1
    return model

file = codecs.open('C:\88888\88888\88888\88888\8888\A Word.txt', encoding='utf-8', mode='r')

NWORDS = train(words(file.read()))

alphabet = 'abcdefghijklmnopqrstuvwxyz'

def edits1(word):
    splits     = [(word[:i], word[i:]) for i in range(len(word) + 1)]
    deletes    = [a + b[1:] for a, b in splits if b]
    transposes = [a + b[1] + b[0] + b[2:] for a, b in splits if len(b)>1]
    replaces   = [a + c + b[1:] for a, b in splits for c in alphabet if b]
    inserts    = [a + c + b     for a, b in splits for c in alphabet]
    return set(deletes + transposes + replaces + inserts)

def known_edits2(word):
    return set(e2 for e1 in edits1(word) for e2 in edits1(e1) if e2 in NWORDS)

def known(words): return set(w for w in words if w in NWORDS)

def correct(word):
    candidates = known([word]) or known(edits1(word)) or known_edits2(word) or [word]
    return max(candidates, key=NWORDS.get)

错误：

  File "C:\8888\8888\8888\8888\88888\SpellCheck.py", line 11
    file = codecs.open('C:\888\888\888\8888\88888\A Word.txt', encoding='utf-8', mode='r')
                      ^

好的，让我们尝试一下……获取一个字符串值 '\x' 并尝试对其执行某些操作或尝试

string('\x.....')

返回您的错误对吗？

因此，如果您定义了一个字符串，请说

x = string('\y\o\u \c\a\n \n\e\v\e\r \c\h\a\n\g\e \t\h\i\s \i\n \p\y\t\h\o\n')

比你运气不好。如果用户决定输入一个'\'作为输入的任何字符，那将是一个遗憾。

要解决此问题，您可以尝试使用一些循环或递归代码，例如： 如何从路径和文件名中删除非法字符？

C:\88888\88888\88888\88888\8888\A Word.txt- 这是我今年见过的最奇怪的路 :)

尝试将其替换为C:\\88888\\88888\\88888\\88888\\8888\\A Word.txt
