01 - Right triangle

Create a text file triangle.py. In it, define function is_right(a, b, c) which

• accepts 3 natural numbers (positive integers) representing the side lengths of a triangle, and
• checks whether the triangle is right, i.e. the function
  • returns True when the numbers a, b, c represent side lengths of a right triangle, and
  • returns False otherwise.

Assume that you will always get 3 positive integers as arguments. But DO NOT ASSUME that you will get them in any specific order!

• 3 points for automatic checks
• 2 point for manual evaluation (is the code readable, did you use the docstring to comment your function)
