Arnold Package

This Python project provides classes to represent and calculate properties for various geometric shapes: Square, Rectangle, Circle, and Triangle. Each class supports methods to calculate the area and perimeter.

Classes

Square

• Constructor: Square(length: float)

  • Parameters:
    • length: Length of the square's side (positive integer or float).

• Methods:

  • area(): Returns the area of the square.
  • perimeter(): Returns the perimeter of the square.

Rectangle

• Constructor: Rectangle(width: float, height: float)

  • Parameters:
    • width: Width of the rectangle (positive integer or float).
    • height: Height of the rectangle (positive integer or float).

• Methods:

  • area(): Returns the area of the rectangle.
  • perimeter(): Returns the perimeter of the rectangle.

Circle

• Constructor: Circle(radius: float)

  • Parameters:
    • radius: Radius of the circle (positive integer or float).

• Methods:

  • area(): Returns the area of the circle.
  • perimeter(): Returns the circumference of the circle.

Triangle

• Constructor: Triangle(base: float = None, height: float = None, side1: float = None, side2: float = None, side3: float = None)

  • Parameters:
    • base: Base of the triangle (positive integer or float).
    • height: Height of the triangle (positive integer or float).
    • side1: Length of the first side (positive integer or float).
    • side2: Length of the second side (positive integer or float).
    • side3: Length of the third side (positive integer or float).

• Methods:

  • area(): Returns the area of the triangle (uses either base and height or all three sides).
  • perimeter(): Returns the perimeter of the triangle.

Usage Example

Here’s a simple example of how to use the classes:

from arnold import Square, Rectangle, Circle, Triangle

# Create a Square object
square = Square(4)
print(f"Square Area: {square.area()}")
print(f"Square Perimeter: {square.perimeter()}")

# Create a Rectangle object
rectangle = Rectangle(3, 5)
print(f"Rectangle Area: {rectangle.area()}")
print(f"Rectangle Perimeter: {rectangle.perimeter()}")

# Create a Circle object
circle = Circle(2)
print(f"Circle Area: {circle.area()}")
print(f"Circle Perimeter: {circle.perimeter()}")

# Create a Triangle object
triangle = Triangle(base=3, height=4, side1=3, side2=4, side3=5)
print(f"Triangle Area: {triangle.area()}")
print(f"Triangle Perimeter: {triangle.perimeter()}")
