所以，我想在我的整個目錄中搜索包含正則表達式列表的文件。這包括：目錄、pdf 和 csv 文件。僅搜索文本文件時，我可以成功完成此任務，但搜索所有文件類型卻很困難。以下是我迄今為止的工作：import globimport reimport PyPDF2#-------------------------------------------------Input----------------------------------------------------------------------------------------------folder_path = "/home/"file_pattern = "/*"folder_contents = glob.glob(folder_path + file_pattern)#Search for Emailsregex1= re.compile(r'\S+@\S+')#Search for Phone Numbersregex2 = re.compile(r'\d\d\d[-]\d\d\d[-]\d\d\d\d')#Search for Locationsregex3 =re.compile("([A-Z]\w+), ([A-Z]{2})")for file in folder_contents:    read_file = open(file, 'rt').read()if readile_file == pdf:    pdfFileObj = open('pdf.pdf', 'rb')     pdfReader = PyPDF2.PdfFileReader(pdfFileObj)     pageObj = pdfReader.getPage(0)      content= pageObj.extractText())     if regex1.findall(read_file) or regex2.findall(read_file) or regex3.findall(read_file):        print ("YES, This file containts PHI")        print(file)    else:        print("No, This file DOES NOT contain PHI")        print(file)當我運行它時，我收到此錯誤：YES, This file containts PHI/home/e136320/sample.txtNo, This file DOES NOT contain PHI/home/e136320/medicalSample.txt---------------------------------------------------------------------------UnicodeDecodeError                        Traceback (most recent call last)<ipython-input-129-be0b68229c20> in <module>()     19      20 for file in folder_contents:---> 21     read_file = open(file, 'rt').read()     22 if readile_file == pdf:     23     # creating a pdf file objectUnicodeDecodeError: 'utf-8' codec can't decode byte 0xc7 in position 10: invalid continuation byte有什么建議？
