Answer 1

You may need to import the math module.

import math

Sandboxes such as codeplayground usually have something happening behind the scenes to make things work where they other wise wouldn't. If you're using an Ide make sure you have the proper modules imported.

Answer 2

' import math ' isn't working, same error message! PyCharm shows a warning at line 6 ( see my code bit ), ' wanring : unexpected arguemant ' for Vector2D() class, that is, Vector2D(self.x + other.x, self.y + other.y )...
