How to catch Permission Error with Popen process

Question

This is the error: Permission Error: Copying of text from this document is not allowed.

I am opening a .exe file on windows. So regular try except block does not seem to catch it. Neither does OSError.

https://stackoverflow.com/questions/25079140/python-subprocess-popen-check-for-success-and-errors#25079374 may be able to help. You'll have to deal with errors directly from a `subprocess` object. — Major, Sep 12 '18 at 19:38
I tried subprocess.CalledProcessError The problem is I want to call Permission Error, I get an error if I do subprocess.CalledProcessError. — TheProgramMAN123, Sep 13 '18 at 02:12

I solved it with the following:

try:
    """code here"""
except subprocess.CalledProcessError:
    """unlock files and try again"""

What ended up being the issue with this method? You said in you were getting an error if you tried this. – Major Sep 21 '18 at 13:37

Try

exception PermissionError

Raised when trying to run an operation without the adequate access rights - for example filesystem permissions. Corresponds to errno EACCES and EPERM.

If you specified irrelevant Exception while trying to catch permission error, I wouldn't be surprised they it is caught

Doesn't work. It does not seem to catch error. It shows in console in red though. Anyway to catch it from there? – TheProgramMAN123 Sep 12 '18 at 19:21
Can you share an example code snippet, and what does not work ? – David Hu Sep 17 '18 at 23:39
