Sure, you can use try/except but it would be nice if the "shutil.copyfile" function supports the same files.

If I have many files (more thousand), I don't want to check them with a try/except.

Furthermore if I want to cover the unexpected exceptions as well I need to use nested try/except (I guess it's not the most elegant way).

Eg.:

try:
    shutil.copyfile("test.txt", "test.txt")
except SameFileError:
    pass
except Exception as unexpected_exception:
    raise unexpected_exception
