Find and repair your import cycles in any project
Pycycle is an experimental project that aims to help python developers fix their circular dependencies problems.
ImportError: Cannot import name X is a python exception that is related to the circular imports, but the exception tells nothing about where or what.
This tool automatically analyzes the imports of your projects, and looks for imports that may cause a circular dependency problem.
- Shows you the whole chain of the circular imports.
- Gives you lines of code where each import is, for you to easily find and fix the problem.
- Visualizes your imports in a graph (Not Yet Implemented)
