• Description should be language-agnostic

• Parameter name in initial solution setup should be snake_case

• Python new test framework should be used

Use approx equality instead of rounding

Your task is to write a function angle_planes(lstPts) that calculates the angle between two planes, each of them being defined by a tuple of three points.

We actually receive a list of 6 tuples of 3 coordinates (I guess). This is a bad design. We should receive two tuples of 3 tuples each.

Hi,

The angle between two planes shouldn't be restricted to [0, 90], because it arbitrary assumes the orientations of normal vectors, therefore some methods giving mathematicaly right anwsers fail. Such assumption would cause problems in scientific calculations.

Hi,

I made several modifications in the description, I hope you won't mind.

• typos
• set -> tuples of points
• correction of the argument name A -> lstPts (in the initial solution too. That is because in python, name beginning with uppercase are for objects)
• little things like that...

cheers
