ImportError: No module named 'wagtail.core' - django

Question

I am using python3 in a virtual environment and have wagtail installed via pip. When I am trying to extend home model for home page. I get the error:-
ImportError: No module named 'wagtail.core'
Here is the code of models.py:-
from django.db import models
from wagtail.core.models import Page
from wagtail.core.fields import RichTextField
from wagtail.admin.edit_handlers import FieldPanel
class HomePage(Page):
body = RichTextField(blank=True)
content_panels = Page.content_panels + [
FieldPanel('body', classname="full"),
]
Here is the error stack:-
*Unhandled exception in thread started by <function check_errors

I am following the basic tutorial for wagtail. Here is the link http://docs.wagtail.io/en/latest/getting_started/tutorial.html
Version of wagtail==1.13.1 and Django==1.11.10. Kindly point to right direction. Thanks in advance.

Edited.
You wrote import statements for wagtail 2.x.
Replace import statements with following statements which is for wagtail 1.13.1:
from wagtail.wagtailcore.models import Page
from wagtail.wagtailcore.fields import RichTextField
from wagtail.wagtailadmin.edit_handlers import FieldPanel
Kindly follow this link
