第一列具有感性，第二列具有鸣叫
为了清除推文，我复制了以下功能：
def cleanTxt(text):
text = re.sub('@[A-Za-z0–9]+', '', text) #Removing @mentions
text = re.sub('#', '', text) # Removing '#' hash tag
text = re.sub('RT[\s]+', '', text) # Removing RT
text = re.sub('https?:\/\/\S+', '', text) # Removing hyperlink
return text
当我尝试使用它时：
str(df.iloc[: 1])
df = df.iloc[: 1].apply(cleanTxt)
print(df.head)
我收到以下错误：
TypeError: expected string or bytes-like object
我该如何解决？
当re.sub遇到非字符串值时，可能会发生这种情况。您可能应该仔细检查字符串中是否有任何特殊字符或转义字符。我只是打印一些推文并检查是否有错误。
