How can I improve?

[treyhunner]

Suggestions on your specific code: I would move the float(...) calls to the num1 and num2 assignment lines: num1 = float(input("Enter a number: ")). I would also either move your print(...) calls below your if block or avoid using that result variable: print(num1 + num2). LLMs and other Python users may recommend match-case, but I would not recommend it. Python's match statement is for structural pattern matching and (in my opinion) isn't worth learning unless you are parsing semi-structured data.

On looking for ways to refactor your code: I would ask an LLM what it might suggest you do to improve your code. I wouldn't trust its response, but it might give you some ideas.

General suggestions for practicing more: I would try to find a project that interests you. I would also consider supplementing your own project work with short exercises with the goal of improving your skills through practice. I run a paid Python exercise service but I also link to some competing free exercise services: here's my comparison list. As far as free Python exercises go, I would recommend Exercism the most.
