过滤目录中的所有文件以匹配多个正则表达式的单词

Question

我正在尝试过滤我目录中的所有文件（pdf、txt、csv、ipynp 等）以查找与我的正则表达式匹配的单词。到目前为止，我制作了一个可以读取 csv 和 pdf 文件的程序（如下所示），但是读取所有其他文件类型的 else 语句一直给我一个错误（显示在底部）。我是不是在 else: 语句之后输入了错误的内容？我什么都试过了，还是没用。

   import glob
import re
import PyPDF2
#-------------------------------------------------Input----------------------------------------------------------------------------------------------
folder_path = "/home/"
file_pattern = "/*"
folder_contents = glob.glob(folder_path + file_pattern)

#Search for Emails
regex1= re.compile(r'\S+@\S+')
#Search for Phone Numbers
regex2 = re.compile(r'\d\d\d[-]\d\d\d[-]\d\d\d\d')
#Search for Locations
regex3 =re.compile("([A-Z]\w+), ([A-Z]{2})")


for file in folder_contents:

    if re.search(r".*(?=pdf$)",file):
        #this is pdf
        with open(file, 'rb') as pdfFileObj:
            pdfReader = PyPDF2.PdfFileReader(pdfFileObj) 
            pageObj = pdfReader.getPage(0)  
            read_file = pageObj.extractText() 
            #print("{}".format(file))
    elif re.search(r".*(?=csv$)",file):
        #this is csv
        with open(file,"r+",encoding="utf-8") as csv:
            read_file = csv.read()
    else:
            with open(file,"rt", encoding='latin-1') as allOtherFiles:
                continue
    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)

我收到一条错误消息说 IsAdirectoryError：[Errno 21] 是一个目录：你知道为什么每当我运行代码时都会显示此错误消息。

  ---------------------------------------------------------------------------
IsADirectoryError                         Traceback (most recent call last)
<ipython-input-40-fdb88fbf61ab> in <module>()
     29             read_file = csv.read()
     30     else:
---> 31             with open(file,"rt", encoding='latin-1') as allOtherFiles:
     32                 continue
     33     if regex1.findall(read_file) or regex2.findall(read_file) or regex3.findall(read_file):

IsADirectoryError: [Errno 21] Is a directory: '/home/jupyter_shared_notebooks'

Answer 1

能否尝试将 with open(file,"rt") as allOtherFiles: 语句更改为

with open(file,"rt", encoding='latin-1') as allOtherFiles:

运行再次输入代码，看看是否遇到同样的错误。如果还是出错，我们就得试试其他的编码格式了。

编辑：要解决您的下一个错误：

IsADirectoryError: [Errno 21] Is a directory: /home/e136320/jupyter_shared_notebooks

这是由您的文件夹中名为 jupyter_shared_notebooks 的文件或文件夹引起的。
因为 python 不知道如何打开 jupyter_shared_notebooks 因为它没有文件扩展名格式。它抛出了这个错误。
要解决这个问题，您可以尝试

if '.' not in file:
    continue
else:
    with open(file,"rt", encoding='latin-1') as allOtherFiles:
        #rest of your code here
