使用Python从多个PDF文件中查找多个单词

import os
import re
from PyPDF2 import PdfFileReader

def search_words_in_pdfs(folder_path, words):
    pdf_files = [file for file in os.listdir(folder_path) if file.endswith('.pdf')]

    for pdf_file in pdf_files:
        pdf_path = os.path.join(folder_path, pdf_file)
        pdf = PdfFileReader(open(pdf_path, 'rb'))

        for page_num in range(pdf.numPages):
            page = pdf.getPage(page_num)
            text = page.extractText()

            for word in words:
                if re.search(r'\b{}\b'.format(word), text, re.IGNORECASE):
                    print("单词 '{}' 在文件 '{}' 的第 {} 页中被找到。".format(word, pdf_file, page_num + 1))

# 示例用法
folder_path = 'path/to/pdf/files'
words = ['word1', 'word2', 'word3']
search_words_in_pdfs(folder_path, words)
