What are the best practices for imports in Python?

Some best practices for imports in Python include:

1. Import modules at the top of the file.
2. Use absolute imports over relative imports.
3. Avoid wildcard imports (e.g., from module import *).
4. Group imports in the following order: standard library imports, related third-party imports, and local application/library imports.

Why should I avoid wildcard imports?

Wildcard imports can lead to a cluttered namespace, making it difficult to track which names are present. This can cause conflicts and make debugging harder.

Can you give an example of absolute vs relative imports?

Sure! An absolute import would look like this: from mypackage.module import MyClass. A relative import would look like this: from .module import MyClass, which is relative to the current module's location.

What about circular imports? How can I avoid them?

To avoid circular imports, you can restructure your code to minimize dependencies, use local imports within functions, or combine modules that are interdependent.
