关于此问题，我在stackoverflow中浏览了多个消息源，但无法解决。因此，我已将其张贴在这里，请解决。

# Combining all the above statemennts 
from tqdm import tqdm
Other_skill = []
# tqdm is for printing the status bar
for sentance in tqdm(project_data['Other skills'].values):
    sent = decontracted(sentance)
    sent = sent.replace('\\r', ' ')
    sent = sent.replace('\\"', ' ')
    sent = sent.replace('\\n', ' ')
    sent = re.sub('[^A-Za-z0-9]+', ' ', sent)
    sent = ' '.join(e for e in sent.split() if e not in stopwords)
    Other_skill.append(sent.lower().strip())

错误：

Answer 1

我认为values（）中的括号是必需的。如果我是正确的，project_data是一本字典，而您错过了值中的括号

from tqdm import tqdm
Other_skill = []
# tqdm is for printing the status bar 
# the values must have round brackets
for sentance in tqdm(project_data['Other skills'].values()):
    sent = decontracted(sentance)
    sent = sent.replace('\\r', ' ')
    sent = sent.replace('\\"', ' ')
    sent = sent.replace('\\n', ' ')
    sent = re.sub('[^A-Za-z0-9]+', ' ', sent)
    sent = ' '.join(e for e in sent.split() if e not in stopwords)
    Other_skill.append(sent.lower().strip())

查看堆栈跟踪，我们可以发现sub中的decontracted输入错误。

最好是在箭头用来检查短语值的地方放置一个断点：

      4 def decontracted(phrase):
      5     # specific
----> 6     phrase = re.sub(r"won't", "will not", phrase)

如果您不知道该怎么做，则可以添加一些调试代码，如下所示：

  def decontracted(phrase):
      # specific
      print(f'phrase: {phrase}\ttype: {type(phrase)}')
      phrase = re.sub(r"won't", "will not", phrase)
      [...]

这将打印给 decontracted 的每个短语及其类型。只能是bytes或str。如果没有，那么您将找到错误并可以相应地进行纠正。

希望对您有帮助，我们没有足够的信息来帮助您。
