如何抑制 Python 库 TextBlob 的一些输出

Question

我正在使用 Python 为从 TextBlob 返回的结果分配标签。我非常基本的代码如下所示：from textblob import TextBlobdef sentLabel(blob):    label = blob.sentiment.polarity     if(label == 0.0):        print('Neutral')    elif(label > 0.0):        print('Positive')    else:        print('Negative')    Feedback1 = "The food in the canteen was awesome"    Feedback2 = "The food in the canteen was awful"    Feedback3 = "The canteen has food"    b1 = TextBlob(Feedback1)    b2 = TextBlob(Feedback2)    b3 = TextBlob(Feedback3)    print(b1.sentiment_assessments)    print(sentLabel(b1))    print(b2.sentiment_assessments)    print(sentLabel(b2))    print(b3.sentiment_assessments)    print(sentLabel(b3))这会正确打印出情绪，但也会打印出“无”，如下所示：Sentiment(polarity=1.0, subjectivity=1.0, assessments=[(['awesome'], 1.0, 1.0, None)])PositiveNone...有什么办法可以禁止打印“无”？感谢您的任何帮助或指点。

Answer 1

你的函数sentLabelreturn None。因此，当您使用时print(sentLabel(b1))，它会打印None.

这应该适合你。

from textblob import TextBlob

def sentLabel(blob):

    label = blob.sentiment.polarity 

    if(label == 0.0):

        print('Neutral')

    elif(label > 0.0):

        print('Positive')

    else:

        print('Negative')

    Feedback1 = "The food in the canteen was awesome"

    Feedback2 = "The food in the canteen was awful"

    Feedback3 = "The canteen has food"

    b1 = TextBlob(Feedback1)

    b2 = TextBlob(Feedback2)

    b3 = TextBlob(Feedback3)

    print(b1.sentiment_assessments)

    sentLabel(b1)

    print(b2.sentiment_assessments)

    sentLabel(b2)

    print(b3.sentiment_assessments)

    sentLabel(b3)
