[英]How can I fix this "IndentationError: expected an indented block"?
def remove_stopwords(text,nlp,custom_stop_words=None,remove_small_tokens=True,min_len=2):
if custom_stop_words:
nlp.Defaults.stop_words |= custom_stop_words
filtered_sentence =[]
doc = nlp (text)
for token in doc:
if token.is_stop == False:
if remove_small_tokens:
if len(token.text)>min_len:
filtered_sentence.append(token.text)
else:
filtered_sentence.append(token.text)
return " ".join(filtered_sentence)
if len(filtered_sentence)>0
else None
I am getting the error for the last else:我收到最后一个错误:
The goal of this last part is, if after the stopword removal, words are still left in the sentence, then the sentence should be returned as a string else return null. I'd be so thankful for any advice.这最后一部分的目标是,如果在删除停用词后,单词仍然留在句子中,那么句子应该作为字符串返回,否则返回 null。我将非常感谢任何建议。
else None

IndentationError: expected an indented block
I guess you want to use the ternary operator .我猜您想使用三元运算符。
The format for it is x if condition else y
this is on the same line and without the :
after the if else.它的格式是
x if condition else y
this 在同一行并且没有:
在 if else 之后。
So your last return statement should be:所以你最后的退货声明应该是:
return " ".join(filtered_sentence) if len(filtered_sentence)>0 else None
Your entire code is not properly indented您的整个代码没有正确缩进
