如何将pandas文本列转换为nltk文本对象

import pandas as pd
from nltk.tokenize import word_tokenize
from nltk.text import Text

data = pd.read_csv('data.csv')  # 假设数据保存在data.csv文件中

text_column = data['text_column']  # 假设文本列名为'text_column'
tokens = text_column.apply(word_tokenize)

text_object = Text(tokens.sum())
