You just created a file l.txt in your home directory.
Now you start python.

Now you try to open a file in /yourpath2yourhome/tmp/l.txt
where "/yourpath2yourhome" is something like "/home/bob".
Of cause there is no file l.txt because you createted it in your home
and not in /yourpath2yourhome/tmp

Your above test is useless when you try to open a nonexisting file.
My point was that "$HOME" doesen't get substituted by python.
It only gets substituted when using "$HOME" in your shell.
Try:
b...@sysero-rkm1laptop:~$ echo $HOME
and the shell prints something like:
/home/bob

Stop clicking on main.py!
Start using a commandline.
b...@sysero-rkm1laptop:~$ python main.py
If something went wrong, you are now able to see it in the terminal window.
