how would you copy a file?

[snippsat]

do you remember how you learned that shutil was the best way to copy a file?

shutil has been in Python standard library for very long time,think since Python 1.4.

the name shutil seems like it mean "shell utilities". since i don't consider copying a file to be a shell function, i would not expect it to be in there

It's build looking at how UNIX/Linux based systems dos it.
shutil.copy() is comparable to the cp command in UNIX based systems.
Can call cp a Linux shell command as many do,so shell utilities(shutil) is not so bad,but the name could have been better.

shutil.copytree() does not fulfill my recent needs, because it requires the destination tree to not exit.

In many case when is not a simple requirement,need to combine shutil with eg os,pathlib, catch the error(try-expect) do something else.
