Simple Python program to calculate the area of a triangle, rectangle, square, or circle.
Based on a challenge from Codedex.io
Challenge instructions:
Create a calculator.py program that calculates the area of one of the following shapes:
Square Rectangle Triangle Circle
The program should present a menu for the user to choose which shape to calculate, then ask them for the appropriate values (side, length, width, etc.).
Then, it should calculate the area and print it out.
I extended the instructions by adding input validation and a loop to repeat the program.
