How can I avoid circular imports in Python?

How can I avoid circular imports in Python?

To avoid circular imports in Python, you can restructure your code by using one of the following methods: 1. Combine related modules into a single module. 2. Use local imports inside functions instead of global imports. 3. Refactor your code to reduce dependencies.

Can you give me an example of using local imports?

Sure! Instead of importing a module at the top, you can import it inside a function. For example:

def my_function():
    from my_module import my_class
    instance = my_class()

This way, the import only happens when the function is called, avoiding circular dependencies.

What if I have to keep the modules separate?

If you need to keep the modules separate, consider using an interface or a third module that both original modules can import. This way, you can manage dependencies without creating circular imports.

Are there any tools to help detect circular imports?

Yes, tools like pylint and flake8 can help detect circular imports in your code. They analyze your code structure and report any circular dependencies.
