> I'm not sure about the best module to host this, though: os.path ?

Some OS don't provide atomic rename. If we only define a function when it is atomic (as we do in the posix module, only expose functions available on the OS), programs will have to write two versions of their function. I prefer to write a "best-effort" function, and so I consider that shutil is the best place for such function.

If this function requires a function specific to the OS, the specific function can be added to posix (or another module).


with shutil.write_file(filename) as f:
  f.write("I hope it will be atomic!")

We need an "atomic rename file" function to implement "atomic write file": see #8828.
