#101343 — What meaning is 'from . import'

Hi,

I see the following code. After searching around, I still don't know the
meaning of '.'. Could you tell me that ? Thanks,





from . import _hmmc
from .utils import normalize

That's called a package-relative import.

https://www.python.org/dev/peps/pep-0328/

If you create a package called (let's be really creative here)
"package", an external script could do this:

from package import _hmmc
from package.utils import normalize

Within the package, you can say "from myself import stuff". It's
exactly the same thing, only it doesn't repeat the package name. If
you think of a package as a directory (which it often will be anyway),
the dot is similar to the common notation for "current directory".
