This code implements a simple calculator in Python that allows the user to perform basic mathematical operations: addition, subtraction, multiplication, division, and exponentiation. The calculator operates in a loop that continues until the user chooses to exit.
• The program prompts the user to input two numbers.
• Then it asks which operation to perform: addition (+), subtraction (-), multiplication (*), division (/), or exponentiation (**).
• The program attempts to convert the input values to floating point numbers. If the conversion fails, it displays an error message.
• Depending on the operation chosen, the result is calculated and displayed.
• The user is asked if he wants to perform another operation. If he answers "no", the loop is interrupted and the program ends; otherwise, the loop starts again.
