从pandas dataframe中删除句子长度超过特定词长的行

import pandas as pd
import re

data = {'Text': ['This is a sentence.', 'Short.', 'Another sentence that is longer.', 'Just a few words.']}
df = pd.DataFrame(data)

def remove_long_sentences(dataframe, word_length):
    dataframe['Sentence Length'] = dataframe['Text'].apply(lambda x: len(re.findall(r'\w+', x)))
    filtered_df = dataframe[dataframe['Sentence Length'] <= word_length]
    filtered_df.drop('Sentence Length', axis=1, inplace=True)
    return filtered_df

word_length = 4
filtered_dataframe = remove_long_sentences(df, word_length)
print(filtered_dataframe)

                  Text
0  This is a sentence.
1              Short.
