Step 1: Define the Calculator Functions Create a Python script with the following code: def add(x, y): return x + y def subtract(x, y): return x - y def multiply(x, y): return x * y def divide(x, y): if y == 0: return "Error: Division by zero" return x / y # Main function to handle user input def calculator(): print("Select operation:") print("1. Add") print("2. Subtract") print("3. Multiply") print("4. Divide") choice = input("Enter choice (1/2/3/4): ") num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) if choice == '1': print(num1, "+", num2, "=", add(num1, num2)) elif choice == '2': print(num1, "-", num2, "=...
