Question

这是我的字符串，我已将字符串拆分为单词

数据是正确单词的集合

句子是包含一些不正确单词的字符串，需要用更正后的单词替换

data="blue whale","red rose","city of joy","dream pride","rain drops","ten house","think twice"
data=[words for segments in data for words in segments.split()]

sentence = ["I'll have to thnik twycee before going to ceety of joiy along with red rossy"]
sentence = sentence.split()

现在我正在尝试拼写检查

 def words(text): return re.findall(r'\w+', text.lower())
    WORDS = Counter(data)

    def P(word, N=sum(WORDS.values())): 
        "Probability of `word`."
        return WORDS[word] / N

    def correction(word): 
        "Most probable spelling correction for word."
        return max(candidates(word), key=P)

    def candidates(word): 
        "Generate possible spelling corrections for word."
        return (known([word]) or known(edits1(word)) or known(edits2(word)) or [word])

    def known(words): 
        "The subset of `words` that appear in the dictionary of WORDS."
        return set(w for w in words if w in WORDS)

    def edits1(word):
        "All edits that are one edit away from `word`."
        letters    = 'abcdefghijklmnopqrstuvwxyz'
        splits     = [(word[:i], word[i:])    for i in range(len(word) + 1)]
        deletes    = [L + R[1:]               for L, R in splits if R]
        transposes = [L + R[1] + R[0] + R[2:] for L, R in splits if len(R)>1]
        replaces   = [L + c + R[1:]           for L, R in splits if R for c in letters]
        inserts    = [L + c + R               for L, R in splits for c in letters]
        return set(deletes + transposes + replaces + inserts)

    def edits2(word): 
        "All edits that are two edits away from `word`."
        return (e2 for e1 in edits1(word) for e2 in edits1(e1))

现在我想做的是，我想用更正后的单词替换所有不正确的单词，并在对象句子中更新

校正（＆＃39; thnik＆＃39）

O / P

认为

用于更新对象的代码＆＃34;句子＆＃34;

for i  in sentence:
        sentence = correction(i)
        sentence = [sentence.append(i)]
        print(sentence)

由于程序将检查所有给定的单词并输出结果，我会使用sentence = ' '.join(sentence)加入它们但for循环代码给出了我的错误"AttributeError: 'str' object has no attribute 'append'"，任何帮助都会非常感激。感谢

Answer 1

sentence = "Thsi is my cdoe"   #Lets assume this is your sentence.    
formatted_sentence = ''
for i  in sentence:
    corrected_word = correction(i) # if "Thsi" is passed to correction it should return "This" 
    formatted_sentence += ' '.join(corrected_word)
print(formatted_sentence)

用python中的正确单词替换字符串
