Hi Milad,

for anybody here to be able to help you diagnose this problem, you’re going to have to provide a bit more information:

What operating system are you using? What version (and distribution)? How did you install Python 3.8?

You’ve shown us that the python3 command doesn’t work. Can you start Python or some Python program in any other way that you know of?

What do you mean, “suddently”? Did you do anything between Python working and Python not working?

Anyway it looks like your Python installation is somehow missing some core components. This is not something that happens just like that, and depending on what caused it it’s possible a lot more of your system is broken.

You may be able to fix this by reinstalling all core Python 3.8 packages. (At the very least libpython3.8-minimal, which should contain /usr/lib/python3.8/encodings/*.

ls /usr/lib/python3.8/encodings

output:
'/usr/lib/python3.8/encodings': No such file or directory

I think most Python3.8 files are deleted right?
