从列中删除 html 文本时，类型 'float' 的对象没有 len() 发生错误

Question

我正在使用亚马逊数据集进行情绪分析。数据集内容为
https://i.stack.imgur.com/qcKZp.png

数据集位于： https://www.kaggle.com/PromptCloudHQ/amazon-reviews-unlocked-mobile-phones

我正在尝试从 Review 列中删除 html。
这就是我正在做的。注意：数据集分配给df.

df_removedNoise = []
def removingHTML(text):
    soup = BeautifulSoup(text, 'lxml').get_text()
    return soup

def removingNoise(text):
    html_removed = removingHTML(text)
    return html_removed

for i in df["Reviews"]:
    text = removingNoise(i)
    df_removedNoise.append(text)

即使 Reviews 列将对象作为数据类型，我仍然收到类似这样的错误。

TypeError                                 Traceback (most recent call last)

     10 for i in df["Reviews"]:
---> 11     df_removedNoise.append(removingNoise(i))

      6 def removingNoise(text):

      8     return html_removed

      2 def removingHTML(text):

      4     return soup
      5 

~/anaconda3/lib/python3.7/site-packages/bs4/__init__.py in __init__(self, markup, features, builder, parse_only, from_encoding, exclude_encodings, **kwargs)
    244         if hasattr(markup, 'read'):        # It's a file-type object.
    245             markup = markup.read()
--> 246         elif len(markup) <= 256 and (
    247                 (isinstance(markup, bytes) and not b'<' in markup)
    248                 or (isinstance(markup, str) and not '<' in markup)

TypeError: object of type 'float' has no len()

任何帮助将不胜感激！

Answer 1

使用 df[df['Reviews'].isnull()] 检查 NaN，如果发现任何问题，请先尝试 dropna
