New submission from john_miller <[email protected]>:
Trying to write into a file fails with a PermissionError (PermissionError:
[Errno 13] Permission denied:).
Typing in a non-elevated shell (User is Administrator)
C:\Users\Username\Desktop>C:\Python38-32\python.exe
open("some_file.txt","w") fails on the Desktop, in the user directory and in
directories where Administrators are permitted to write (while normal users can
only read and execute).
(Permissions for the user in those directories:
Desktop rwx,
Username-directory rwx,
third-location r-x for users/rwx for Administrator-user-group (with
non-elevated applications))
I can write to all these places without elevation using the shell or standard
applications like notepad.exe.
Why do I have to elevate the Python-process to access such functionality? Is
this related to the security-settings on python.exe or its
installation-directory location?
Forcing a user to elevate the user-launched process for tasks that operate on
normal user-writable files feels like a light security-risk. Because they get
used to elevate Python-scripts even if the performed task by itself would not
require it.
What changed compared to Python 2?
