是否可以清除这些奇怪的符号

Question

 def _clean(text):
    text = text.lower()
    text = re.sub(r'RT|rt', '', text)
    text = re.sub(r'&', '&', text)
    text = re.sub(r'[?!.;:,#@-]', '', text)
    text = re.sub(r"[$&+,:;=?#]|[0-9]|<ed>|<U\+[A-Z0-9]+>", "", text)
    text = re.sub("<+[A-Z0-9]+>", "", text)
    text = re.sub(r'https?|:\//\w.*', '', text)
    text = re.sub(r'\//?w*', '',text)
    text = re.sub(r'\ ã°â*', '' ,text)
    words = text.split()
    words = [w for w in words if w not in stopwords]
    text = " ".join(words)
    text = emoji_pattern.sub(r'', text)
    return text

到目前为止，我已经使用了上面的代码。我不知道如何清理此代码

Answer 1

您可以使用以下正则表达式删除所有非ASCII字符：

text = re.sub(r'[^\x00-\x7F]+', '', text)

另请参阅此问题：Replace non-ASCII characters with a single space

Answer 2

这是您需要的：text = re.split(r'[^\w\(\)]', '', text)吗？
