how would you copy a file?

I think shutil has for a very long time been the preferred way to copy or move files is Python.
My answers 10-years ago(i have looked) would pretty much be the same today.
Could add pathlib to be more modern.

from pathlib import Path
from shutil import copy, move

source = Path('old_file.txt')
destination = Path('new_file.txt')
copy(source, destination)
# move(source, destination)
