import function from a file in the same folder

Question

I\'m building a Flask app with Python 3.5 following a tutorial, based on different import rules. By looking for similar questions, I managed to solve an ImportError based on

Answer 1

# imports all functions    
import config
# you invoke it this way
config.my_function()

or

# import specific function
from config import my_function
# you invoke it this way
my_function()

If the app.py is invoked not from the same folder you can do this:

# csfp - current_script_folder_path
csfp = os.path.abspath(os.path.dirname(__file__))
if csfp not in sys.path:
    sys.path.insert(0, csfp)
# import it and invoke it by one of the ways described above
