Module not found issue

Question

I'm a bit new to running code from the terminal. I am running a test module called test_blbmktdata.py from the terminal by running:

python -m unittest test_blbmktdata.py  

And am getting a error:

File "C:\Users\stacey\Documents\MERLIN\MERLIN - WORKING\dao_all\dao\iotools\tests\test_blbmktdata.py", line 3, in <module>
    from dao.iotools.blbmktdata import *
ModuleNotFoundError: No module named 'dao'

The folder dao does exit:

C:\Users\stacey\Documents\MERLIN\MERLIN - WORKING\dao_all\dao\iotools

Please see below for the beginning of the module (where the problem is).

import unittest
import os.path
from dao.iotools.blbmktdata import *

class TestBlbMktData(unittest.TestCase):
    staticName='StaticInstrumentData.csv'

If I run the code from the terminal do I need to change the way I reference imports from different folders?

Thanks

Answer 1

python don't know where to look for the dao model

add the follwoing lines before the import

import sys
sys.path.append(<path to prj root directory>)

also you will need to have a init.py file (empty file) in each directory of the dao so python could recognise it as a module

Answer 2

Please check whether pythonpath environment variable is properly set. You can refer this. How to add to the pythonpath in windows 7?

In addition to shahaf's answer, it is worthwhile to look at the official documentation on module resolution : https://docs.python.org/3/tutorial/modules.html#the-module-search-path
