A python program (calculator)

I am looking for a skilled Python developer to create a calculator program. The program should be able to perform basic arithmetic operations such as addition, subtraction, multiplication, and division. Additionally, it should include advanced mathematical functions like exponents and logarithms.

For the user interface, either a command line interface or a graphic user interface is acceptable.

No additional features such as saving past calculations or performing batch operations are required.

Ideal Skills and Experience:
- Proficiency in Python programming
- Experience in developing calculator programs
- Knowledge of basic arithmetic operations and advanced mathematical functions
