python import package from same directory code example

Example 1: how call module in the same directory

from .posts_run import get_all_posts
#    ^ here do relative import
# or
from core.posts_run import get_all_posts
# because your package named 'core' and importing looks in root folder

Example 2: importing python module from different directory

# test.py
import sys
# append current python modules' folder path
# example: need to import module.py present in '/path/to/python/module/not/in/syspath'
sys.path.append('/path/to/python/module/not/in/syspath')

import module
