Welcome to the Python Calculator!
Select an operation:
1. Addition (+)
2. Subtraction (-)
3. Multiplication (*)
4. Division (/)
5. Exponentiation (^)
6. Modulus (%)
7. Exit

Enter the number of the operation (1-7): Enter the first number: Enter the second number: Result: 10.0 + 20.0 = 30.0

Enter the number of the operation (1-7): Enter the first number: Enter the second number: Result: 50.0 - 30.0 = 20.0

Enter the number of the operation (1-7): Thank you for using the calculator. Goodbye!
