IOError: [Errno 13] 權限在 python 中被拒絕

Question

我在 7 個不同的文件夾目錄中有多個文件。 所有這些文件都具有相同的名稱，我想將這些文件與一個文件的名稱相同，放在另一個目錄中

import os
from itertools import chain

paths = (r'C:/Users/Test_folder/Input/', r'C:/Users/Test_folder/Input_2/')
for path, dirs, files in chain.from_iterable(os.walk(path) for path in paths):
    for fname in paths:
        for line in fname:
                f = open(os.path.join(r'C:/Users/Test_folder/Test_output/', os.path.basename(fname)), 'a')
                f.write ('{:}\n'.format(line))
                f.close()

錯誤：

f = open(os.path.join(r'C:/Users/Test_folder/Test_output/', os.path.basename(fname)), 'a')
IOError: [Errno 13] Permission denied: 'C:/Users/Test_folder/Test_output/'
>>> 

Answer 1

對於permisson denied的問題

  with open(os.path.join('type filename here' , os.path.basename(line)), 'w')

要么

for filename in os.listdir(src):
   path = os.path.join(src, filename)
   with open(path, "r") as inputFile:
   content = inputFile.read()

Answer 2

你的代碼邏輯是錯誤的：

• for fname in paths中for fname in files
• for line in fname不會逐行讀取文件fname ，因為fname是字符串，而不是文件 object

權限錯誤是由於您的代碼嘗試打開一個directory進行追加。

嘗試：

import os
from itertools import chain

paths = (r'C:/Users/Test_folder/Input/', r'C:/Users/Test_folder/Input_2/')
for path, dirs, files in chain.from_iterable(os.walk(path) for path in paths):
    for fname in files:
        with open(os.path.join(path, fname)) as fin, open(os.path.join('C:/Users/Test_folder/Test_output/', fname), 'a') as fout:
            fout.write(fin.read())

如果您使用的是 windows，請以管理員身份重新運行 ide。
