File Handling: Change permissions to octal

If I run any code for the File Handling, I got the readme.txt file with these permissions: "-r----x--t", I research how to fix it and I discovered that it needs to be in octal mode, you are able to use the octal nomenclatures: 0777o or 0o0777. With this change I got these permissions: "-rwxr-xr-x", it is not the full 777 but at least I'm able to update the file.
