Hi
This is the first time that I'm trying to contribute to sympy code.
After adding just one line to `sets.py`, I can not import `sympy` anymore.
This is the line that I added:
from sympy.geometry.point import Point
My guess is that this is caused by a circular import.
What is the right way of dealing with this situation?
- Am I for some reason not supposed to import `Point` into `sets`? or,
- Should I import right in the function where I need to use `Point`? or,
- Are there other parts of the code which need to be refactored? or,
- This does not have anything to do with circular imports?
This is the error that I receive:
