As error message said your application has no permissions to read from the directory  It can be the case when you created the directory as one user and run script as another user

You can t  open  a directory using the open function  This function is meant to be used to open files   Here  what you want to do is open the file that s in the directory  The first thing you must do is compute this file s path  The os path join function will let you do that by joining parts of the path  the directory and the file name    fpath   os path join direct   5 1 txt     You can then open the file   f   open fpath    And read its content   content   f read       Additionally  I believe that on Windows  using open on a directory does return a PermissionDenied exception  although that s not really the case

For folks like me looking at the accepted answer  and not understanding why it s not working  you need to add quotes around your sub directory  in the green checked example   x file   open os path join direct   5 1 txt     r       should actually be  x file   open os path join  direct    5 1 txt     r

Looks like you are trying to open a directory for reading as if it s a regular file  Many OSs won t let you do that  You don t need to anyway  because what you want  judging from your description  is   x file   open os path join direct   5 1 txt     r       or simply  x file   open direct   5 1 txt    r

In case you re not in the specified directory  i e  direct   you should use  in linux    x file   open  path to direct filename txt     Note the quotes and the relative path to the directory   This may be your problem  but you also don t have permission to access that file  Maybe you re trying to open it as another user

i found this way useful also   import tkinter filedialog from filename   tkinter filedialog askopenfilename       here a window will appear so you can browse till you find the file   you click on it then you can continue using open   and read      from file   open from filename   r   contents   from file read   contents

For windows you can either use the full path with           for Linux and Mac  as separator of you can use os getcwd to get the current working directory and give path in reference to the current working directory  data dir   os getcwd      child directory  file   open data dir    filename txt    r     When I tried to give the path of child diectory entirely it resulted in error  For e g  in this case   file   open  child directory  filename txt    r     Resulted in error  But I think it must work or I am doing it somewhat wrong way but it doesn t work for me  The about way always works
