You can run CMD as Administrator and change the permission of the directory using cacls exe  For example   cacls exe c   t  e  g everyone F   means everyone can totally control the C  disc

Here is how I encountered the error  import os  path   input  quot Input file path   quot    name  ext   os path basename path  rsplit      1  dire   os path dirname path   with open f quot  dire    name  temp  ext  quot    wb   as file      pass  It works great if the user inputs a file path with more than one element  like C   Users  Name  Desktop  Folder  But I thought that it would work with an input like file txt  as long as file txt is in the same directory of the python file  But nope  it gave me that error  and I realized that the correct input should ve been    file txt

EDIT  I am seeing a bit of activity on my answer so I decided to improve it a bit for those with this issue still  There are basically three main methods of achieving administrator execution privileges on Windows    Running as admin from cmd exe  Creating a shortcut to execute the file with elevated privileges Changing the permissions on the python executable  Not recommended      1  Running cmd exe as and admin  Since in Windows there is no sudo command you have to run the terminal  cmd exe  as an administrator to achieve to level of permissions equivalent to sudo  You can do this two ways    Manually   Find cmd exe in C  Windows system32 Right-click on it Select Run as Administrator It will then open the command prompt in the directory C  Windows system32 Travel to your project directory Run your program  Via key shortcuts   Press the windows key  between alt and ctrl usually    X  A small pop-up list containing various administrator tasks will appear  Select Command Prompt  Admin   Travel to your project directory Run your program    By doing that you are running as Admin so this problem should not persist  2  Creating shortcut with elevated privileges   Create a shortcut for python exe Righ-click the shortcut and select Properties Change the shortcut target into something like  C  path to python exe  C  path to your script py  Click  advanced  in the property panel of the shortcut  and click the option  run as administrator    Answer contributed by delphifirst in this question  3  Changing the permissions on the python executable  Not recommended   This is a possibility but I highly discourage you from doing so   It just involves finding the python executable and setting it to run as administrator every time  Can and probably will cause problems with things like file creation  they will be admin only  or possibly modules that require NOT being an admin to run

The problem could be in the path of the file you want to open  Try and print the path and see if it is fine I had a similar problem def scrap soup filenm   htm  soup prettify   replace  quot https    quot   quot  quot    replace  quot http    quot   quot  quot   if  quot  php quot  in filenm or  quot  aspx quot  in filenm or  quot  jsp quot  in filenm      filenm filenm split  quot   quot   0      filenm   quot    html quot   format filenm      print  quot Converted a  file into html that was not compatible quot    if  quot  aspx quot  in htm      htm htm replace  quot  aspx quot   quot  aspx html quot       print  quot  process    conversion fron aspx quot   if  quot  jsp quot  in htm      htm htm replace  quot  jsp quot   quot  jsp html quot       print  quot  process   conversion from jsp quot   if  quot  php quot  in htm      htm htm replace  quot  php quot   quot  php html quot       print  quot  process   conversion from php quot    output open  quot data  quot  filenm  quot w quot  encoding  quot utf-8 quot   output write htm  output close   print  quot    bits of data written quot  format len htm     but after adding this code  nofilenametxt filenm split      nofilenametxt nofilenametxt len nofilenametxt -1  if  len nofilenametxt   0       filenm   quot   index html quot   format filenm

Make sure the file you  are trying to write is closed first

in my case  i just make the  idlerc directory hidden  so  all i had do is to that directory and make recent-files lst unhidden after that  the problem was solved

This also happens if you are trying to write a file  but your path is a folder  This can happen easily by mistake  To defend against that  use  import os  path   r quot my path to file txt quot  assert os path isfile path  with open path   quot r quot   as f      pass  The assertion will fail if your path is actually a folder

In my case the problem was that I hid the file  The file had hidden atribute       How to deal with the problem in python  import os    This is how to hide the file os system f quot attrib  h  filePath  quot   file    open filePath   quot wb quot    gt  gt  gt  PermissionError  lt  lt  lt      and this is how to show it again making the file writable again  os system f quot attrib -h  filePath  quot   file    open filePath   quot wb quot     This works    and just to let you know there is also this way   so you don t need to import os import subprocess subprocess check call   quot attrib quot    quot -H quot    path

This error actually also comes when using keras preprocessing image so for example  img   keras preprocessing image load img folder path  target size image size   will throw the permission error  Strangely enough though  the problem is solved if you first import the library  from keras preprocessing import image and only then use it  Like so  img   image load img img path  target size  180 180

Change the permissions of the directory you want to save to so that all users have read and write permissions

Another option that helped me is using pathlib  from pathlib import Path p   Path         if you want to write to current directory with open p    test txt    w   as f      f write  test message     and it works
