from . import test # Relative to this package
instructs Python to import a module named test located in the same package directory as the file in which this statement appears.
Similarly, this statement:
from .test import name
means "from a module named test located in the same package, import the variable name."
Other dot-based relative reference patterns are possible.
Within a module file located in a package directory named mypkg, the following alternative import forms work as described:
from .string import name1, name2 # Imports names from mypkg.string from . import string # Imports mypkg.string from .. import string # Imports string sibling of mypkg
