How to handle circular imports in Python modules without causing ImportError?

python imports circular-dependency Python

I'm performance testing and I'm working with a frustrating scenario with circular imports in my Python project, which is structured with multiple modules... Specifically, I have two files, `module_a.py` and `module_b.py`, which depend on each other. When I try to run `module_a.py` or import it in another script, I encounter the following behavior: `ImportError: want to import name 'func_b' from partially initialized module 'module_b'`. My current implementation looks like this: ```python # module_a.py from module_b import func_b def func_a(): print('Function A is called') func_b() ``` ```python # module_b.py from module_a import func_a def func_b(): print('Function B is called') func_a() ``` I've considered refactoring my code to eliminate the circular dependency, but I'm unsure of the best approach. I've tried rearranging the import statements and moving some functions to a third module, but that has not resolved the scenario. Is there a recommended pattern or best practice for handling imports in such scenarios? I'm currently using Python 3.10.0. Any guidance would be appreciated! This is part of a larger web app I'm building. Thanks in advance! My development environment is macOS. Thanks, I really appreciate it! My team is using Python for this CLI tool. Thanks for any help you can provide!
