Description

OURO (OUROboros) is a Python package that checks your code for circular (cyclic) imports.

Currently, ouro only supports absolute imports

Name Origin

The name "ouro" is derived from the term "ouroboros", a symbol from ancient mythology depicting a snake consuming its own tail, representing the concept of infinity and cyclicality. This name was chosen for its apt metaphorical representation of the package's functionality. Just as the ouroboros symbolizes a cycle, the "ouro" package checks for circular imports in Python. The connection to Python, a language named after a type of snake, further reinforces this symbolic link.
