Delete file without using import os

is there a way to delete file with issuing the command
import os

Technically, no, unless you write an extension module that issue
the unlink system call (on POSIX, and the equivalent on others),
which is essentially reimplementing os.remove or os.unlink.

In case you just want to directly avoid importing os,
you can use a library wrapping around it like pathlib.
