在python中计算倾向函数

import nltk
from nltk.sentiment import SentimentIntensityAnalyzer

def calculate_sentiment(text):
    # 初始化情感分析器
    sid = SentimentIntensityAnalyzer()
    
    # 计算文本的情感倾向性得分
    sentiment_scores = sid.polarity_scores(text)
    
    # 根据得分判断情感倾向
    if sentiment_scores['compound'] >= 0.05:
        sentiment = '正面'
    elif sentiment_scores['compound'] <= -0.05:
        sentiment = '负面'
    else:
        sentiment = '中性'
    
    return sentiment, sentiment_scores

# 示例文本
text = "这部电影真是太棒了！我非常喜欢它。"

# 计算倾向函数
sentiment, sentiment_scores = calculate_sentiment(text)

# 打印结果
print("情感倾向：", sentiment)
print("情感得分：", sentiment_scores)
