This is a simple example of how to use loguru in your flask application

Just create a new InterceptHandler and add it to your app. Different settings should be configured in your config file, so that it is easy to change settings.

Logging is then as easy as:

from loguru import logger

logger.info("I am logging from loguru!")

When are Python circular imports fatal?

In your Python package, you have:

• an __init__.py that designates this as a Python package
• a module_a.py, containing a function action_a() that references an attribute (like a function or variable) in module_b.py, and
• a module_b.py, containing a function action_b() that references an attribute (like a function or variable) in module_a.py.

This situation can introduce a circular import error: module_a attempts to import module_b, but can't, because module_b needs to import module_a, which is in the process of being interpreted.

But, sometimes Python is magic, and code that looks like it should cause this circular import error works just fine!
