Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

It means you don't have read permission to that file.

graceful cipher
#

idk if the code is right

#

how do i change read permission

rose latch
#

A better question is: why do you need to read it? What's that file for?

graceful cipher
#

i need it to lock

cloud thorn
#

It's a folder, it's trying to open a file

rose latch
#

(Curious: is it a folder?)

graceful cipher
#

how do i make it do folder not file

#

yea

cloud thorn
distant stratus
#

os.walk(directory)

rose latch
#

So lock.py is your code? Maybe you should post it or something.

cloud thorn

rose latch
#

I'm a bit concerned that yourFILE_PATH and your ENCRYPTED_PATH seem to be the same. So you read the FILE_PATH, overwrite it with the encrypted stuff, and then remove FILE_PATH, which looks like it would remove the encrypted file.

#

And does os.chmod work sanely on windows?

graceful cipher
#

idk what to put as the encrypted

distant stratus
#

it seems ai generated...

rose latch
distant stratus
#

what you actually want to do? cuz the way it is doing is quite not right...

cloud thorn
distant stratus

oh i see

cloud thorn

More precisely this with changed path

Hey @graceful cipher!

Please edit your message to use a code block

Add a py after the three backticks.

```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```

At the least I'd want "xb" instead of "wb" for the writes. If the output file should be new.
