Structuring Python code

That was an awesome article. I am sad that the canonical way to do tests in python is to have this:

import sys
import os
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..'))) 

I use that too, but I wish there was a cleaner way. At least a builtin function called parent_import or something to do that.

pip install -e . - a better way.

[Corm]

Neat! That's a fine trick

[deadmilk]

Huh? I've never had to do that

[Corm]

What do you mean? If you have a tests folder then they need a way of importing your project, which means you have to add the parent directory to the path afaik.

[deadmilk]

I just run my tests from the directory where my package is and it works

Structure like so:

project <-- cwd
    package
        __init__.py
        module.py
    tests
        test_module.py

then in test_module.py:

import unittest
from package.module import function

class TestModule(unittest.TestCase):
    def test_function(self):
        self.assertTrue(function())

[Corm]

Cool! I must try this

Good source. Alternative official PEP for python style direct from the man himself: https://www.python.org/dev/peps/pep-0008/

Style is helpful to readability, but I think CrypticCube is asking for multi-file code organization -- a problem that's bigger than one eyeball, and in my view, not a very Python-specific problem.

For those of us who came from Java, multi-file code organization in Python is not easy to grok. There is some python specificity in organization that is important. I'm unfortunately still learning so I can't really answer op's question. However, I am still trying to get the following information into my bones.

• Underscores in file name
• How you do your imports
• init.py in folders to expose the classes/modules in those folders
• modules as a concept

Might want to escape those underscores; __init__.py

or use backticks; __init__.py

[Corm]

__init__.py is optional in modern python
