Triangles are geometric figures with 3 sides and equilateral triangles are triangles in which all three sides are equal. Given a triangle, we can calculate its perimeter.
Below you can see classes Triangle and EquilateralTriangle. The class Triangle has a method __init__ with three parameters for three sides and a method get_perimeter that calculates the perimeter of the triangle.
The class EquilateralTriangle should have a method __init__() with 1 parameter since all its sides have equal length. This method is not yet finished.
Your task is to finish the __init__() method for the equilateral triangles in a way that allows us to use the get_perimeter method of the class Triangle without overriding it. Use the function super() for that!
