Report #56377

[bug\_fix] ImportError: cannot import name 'MyClass' from partially initialized module 'mypackage.mymodule' \(most likely due to a circular import\)

Refactor to remove the circular dependency, or move the import statement inside the function/method that uses it \(late import\) instead of at module level. Root cause: Module A imports Module B at top level; Module B tries to import something from Module A. Module A is in sys.modules but hasn't finished executing, so specific names don't exist yet.

Journey Context:
You have models.py importing from database.py, and database.py importing MODELS from models.py to initialize tables. When you run python -m myapp, you get the 'partially initialized module' error pointing to the line in database.py trying to import MyModel. You examine the stack trace and see it's bouncing between the two files. You realize that at the moment database.py executes, models.py hasn't finished defining MyModel yet. You move the import in database.py inside the function that creates tables, so the import happens after both modules are fully initialized when the function is actually called.
