Python查找可能拼写错误的单词频率和字符串频率，并保存为txt文件或CSV

Question

我要做的是从杂乱的文本文件中提取一些特定的单词，这些单词有时拼写错误或者不属于我的字符。我已经能够在一个目录中的多个文件中完成单个单词的精确拼写，这很接近，但并不完全是我想要的。最后一件事是，我想将这个包含单词和短语计数的列表保存到一个文本文件中，而不仅仅是将其打印为摘要，这正是我的代码现在所做的

如果不可能找到相近的匹配项，那没关系，但那将是理想的

谢谢你的帮助

def word_frequency(fileobj, words):
    """Build a Counter of specified words in fileobj"""
    # initialise the counter to 0 for each word
    ct = Counter(dict((w, 0) for w in words))
    file_words = (word for line in fileobj for word in line.split())
    filtered_words = (word for word in file_words if word in words)
    return Counter(filtered_words)


def count_words_in_dir(dirpath, words, action=None):

    for filepath in glob.iglob(os.path.join(path, '*.txt')):

            ct = word_frequency(f, words)
            if action:
                action(filepath, ct)


def print_summary(filename, ct):
    words = sorted(ct.keys())
    counts = [str(ct[k]) for k in words]
    print('{0}\n{1}\n{2}\n\n'.format(
        filepath,
        ', '.join(words),
        ', '.join(counts)))


words = set(['JUSTICE', "policy payment", "payment", "annuity", "CYNTHEA" ])
count_words_in_dir('./', words, action=print_summary)
