在每行1个字符串中包含多个句子的Dataframe上应用Sentimentr

import pandas as pd
from sentimentr import Sentimentr

# 创建包含字符串的Dataframe
df = pd.DataFrame({'text': ['句子1。句子2。', '句子3。句子4。']})

def apply_sentimentr(text):
    # 创建Sentimentr对象
    sentimentr = Sentimentr()

    # 将字符串拆分为句子
    sentences = text.split('。')

    # 对每个句子进行情感分析
    sentiments = []
    for sentence in sentences:
        sentiment = sentimentr.get_sentiment(sentence)
        sentiments.append(sentiment)

    # 返回情感分析结果
    return sentiments

# 在Dataframe上应用函数
df['sentiments'] = df['text'].apply(apply_sentimentr)
