ZeroDivisionError: float division by zero

This error always raises even though I added if/else to prevent the situation that float(self.bp_c) is zero, but why there’s still weird ZeroDivisionError? Why the ‘->’ point to a line there’s no any division? I have no idea.

I run this project on BML CodeLab which is like jupyter notebook.but I don’t know how to add pdb and see the values. I can only fix some codes in cmd
