1. [10 points] (PYTHON) Write a program that prompts user to enter three sides of a triangle. The program should determine if the three sides can form a triangle. If the three sides can form a triangle, then determine the type of the triangle. There are three types of triangles:

• Equilateral triangle (all 3 sides are equal)
• Isosceles triangle (two sides are equal, the third side is of a different length)
• Scalene triangle (all 3 sides are of different lengths)

The program should have a function called triangle_type() that takes 3 parameters, the lengths of each side. The triangle_type() function should return Equilateral, Isosceles, or Scalene according to the descriptions above. Do not use global variables. Function parameters must be used.
