权限错误Errno13 - Windows上的Python

Question

提前谢谢你的帮助。

我正在编写一些代码，用于在不同的文件夹中浏览多个pdf并查找特定的单词。我的python知识充其量是最基本的，因为我只是为我的学士论文学习它。

当我在文件夹本身中运行代码时，代码工作正常，但我并不是想让它自动运行某个文件夹中的每个子文件夹。

import PyPDF2
import os
rootdir = r"C:\Users\Tim Knickmann\Documents\LUBS\(3300) Dissertation\Data\Python Scripts for Earnigns Calls\Germany Transcripts"
extensions = ('.pdf')
pronoun_file = r"C:\Users\Tim Knickmann\Documents\LUBS\(3300) Dissertation\Data\Python Scripts for Earnigns Calls\pronoun_use.txt"
first_person_pronoun_file = r"C:\Users\Tim Knickmann\Documents\LUBS\(3300) Dissertation\Data\Python Scripts for Earnigns Calls\first_per_pronoun_use.txt"


def average_use(lst):
    return sum(lst) / float(len(lst))

# running it for every file
for subdirs_1, dirs_1, files_1 in os.walk(rootdir):
  for subdirs_1 in dirs_1:
        working_folder_directory = os.path.join(rootdir, subdirs_1)

        # reading in file into a seperate text document
        for subdirs_2, dirs_2, files_2 in os.walk(working_folder_directory):
            list_first_person_usage = []
            pdfFileObj = open(subdirs_2, 'rb')
            pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
            with open('working_doc.txt', 'w', encoding="utf-8") as f:
                        for i in range(0,pdfReader.numPages) :
                           pageObj = pdfReader.getPage(i)
                           f.write(pageObj.extractText())

每当我运行代码时，它都会返回此错误日志：

    runfile('C:/Users/Tim Knickmann/Documents/LUBS/(3300) Dissertation/Data/Python Scripts for Earnigns Calls/Germany Transcripts/190319 v10 Script for Earnings Calls.py', wdir='C:/Users/Tim Knickmann/Documents/LUBS/(3300) Dissertation/Data/Python Scripts for Earnigns Calls/Germany Transcripts')

PermissionError: [Errno 13] Permission denied: 'C:\\Users\\Tim Knickmann\\Documents\\LUBS\\(3300) Dissertation\\Data\\Python Scripts for Earnigns Calls\\Germany Transcripts\\Deutsche Wohnen'

我已经解析了可用的内容，但无法找到适用于这种情况的任何内容。

我很确定我正在尝试打开一个已打开的文件，但无法想出另一种方法。

非常感谢所有的帮助，所以再次感谢。

Answer 1

如错误所示，在线：

pdfFileObj = open(orginial_file_directory, 'rb')

orginial_file_directory有价值

C:\\Users\\Tim Knickmann\\Documents\\LUBS\\(3300) Dissertation\\Data\\Python Scripts for Earnigns Calls\\Germany Transcripts

这是有道理的，因为你已经设定了它

orginial_file_directory = os.path.dirname(os.path.realpath(file))

正如变量名所暗示的那样，您可以理解，这是一个当然不能作为文件打开的目录。

我想你想做点什么

pdfFileObj = open(file, 'rb')
