How to handle circular imports in Python modules with complex dependencies?
I just started working with I'm building a feature where After trying multiple solutions online, I still can't figure this out. I've been struggling with this for a few days now and could really use some help... I'm working with a `ImportError: want to import name 'X' from partially initialized module 'module_a'` when trying to run my Python project that consists of multiple modules with interdependent classes. Specifically, I have two modules, `module_a.py` and `module_b.py`, both of which import each other. Here are the relevant portions of the code: In `module_a.py`: ```python from module_b import ClassB class ClassA: def __init__(self): self.b = ClassB() print('Created ClassA') ``` And in `module_b.py`: ```python from module_a import ClassA class ClassB: def __init__(self): self.a = ClassA() print('Created ClassB') ``` When I run `main.py`, which simply imports `ClassA` from `module_a`: ```python from module_a import ClassA if __name__ == '__main__': a = ClassA() ``` I get the circular import behavior. I tried rearranging the import statements, but that didn’t help. I’ve also considered using `import` statements inside functions to delay the import, but I’m not sure if that’s a good practice or if it would lead to other issues. What’s the best way to resolve this circular dependency without compromising the design of my application? I'm using Python 3.9.1, and I'd appreciate any insights on best practices for structuring modules to avoid these kinds of issues in the future. I'm working on a API that needs to handle this. My development environment is Ubuntu. What's the best practice here? How would you solve this? My team is using Python for this desktop app. Any suggestions would be helpful.
