I am trying to import test.py from within main.py how would I be able to do that? Both main.py and test.py and the data.json is allocated within the application folder. The test.py file is within the app folder. I am trying to open and read the data.json file from test.py. But it is giving me the error FileNotFoundError: [Errno 2] No such file or directory: 'data.json'. how would I be able to read and print the data.json file?

Directories:

application folder
├── appFolder
│   ├──test.py
│   ├──data.json
│   
└── main.py

Code within Main.py

from appFolder import test

Code within test.py

import os
import json

TEST_FILENAME = os.path.join(os.path.dirname(__file__), 'MomentumStrats.json')
data = json.load(TEST_FILENAME)
print(data)

Inside data.json:

{
  "states": [
    {
      "name": "Alabama",
      "abbreviation": "AL",
      "area_codes": ["205", "251", "256", "334", "938"]
    }
}

From which directory are you starting the program? – mkrieger1 May 28 '21 at 21:21
`Main.py` runs `test.py` and the `test.py` reads and prints the `data.json` file – tony selcuk May 28 '21 at 21:23
And from where are you starting `Main.py`? – mkrieger1 May 28 '21 at 21:24
I just start `Main.py` manually and it runs the other files – tony selcuk May 28 '21 at 21:26
And *from which directory*? What do you type to start it? – mkrieger1 May 28 '21 at 21:26
I made a diagram of the `Directories` .`Main.py` is within the application folder – tony selcuk May 28 '21 at 21:29
I don't want to know where the file *is* but *from where you start it*. Since you are not aware of the difference, presumably it's the same. So `data.json` should be `appFolder/data.json` in the code. – mkrieger1 May 28 '21 at 21:30
Does this answer your question? [How to make an "always relative to current module" file path?](https://stackoverflow.com/questions/10174211/how-to-make-an-always-relative-to-current-module-file-path) – mkrieger1 May 28 '21 at 21:31
Hi I have tried to use the link you sent, I have updated the issues `test.py` file it recognizes the json file but I still cant get it to read. – tony selcuk May 28 '21 at 22:14
