I want prepare a simple calculator which is following my Tearm and conditions

[emreylmzcom]

1. Which operations should the calculator support (e.g., addition, subtraction, multiplication, division)?
2. Are there any restrictions on the input values (e.g., no negative numbers, specific range of values)?
3. Are there any special behaviors or additional features (e.g., handling invalid input, logging operations)?
4. Please specify your preferred programming language (Python, JavaScript, C#, Java, or another language).

python code

def calculator(operand1, operator, operand2):
    try:
        operand1 = float(operand1)
        operand2 = float(operand2)
    except ValueError:
        return "Error: Invalid number format."

    if operator == '+':
        return operand1 + operand2
    elif operator == '-':
        return operand1 - operand2
    elif operator == '*':
        return operand1 * operand2
    elif operator == '/':
        if operand2 == 0:
            return "Error: Division by zero is not allowed."
        return operand1 / operand2
    elif operator == '%':
        return (operand1 * operand2) / 100
    else:
        return "Error: Invalid operator."

# Example usage
operand1 = input("Enter the first number: ")
operator = input("Enter an operator (+, -, *, /, %): ")
operand2 = input("Enter the second number: ")

result = calculator(operand1, operator, operand2)
print("Result:", result)

Do not forget to add a check for an empty string, that is, if you did not enter a number or a string, then it outputs the error "Enter a number!"

Hi @emreylmzcom & @AndreiExtr, thanks for taking the time to answer!

@RajanMistry12 I saw that you added more comments below - was that the solution or do you still have more questions?
