You are very close! In challenges defining functions, the input() function will not be used. All "input" will come through the parameters defined in the function definition (also call the function signature). The parameter values will be provided as arguments from the challenge checker.

If you move your final return statement inside the try block and remove the input statement, it will pass all tasks.

Also, while the Python code interpreter allows using parens with the return statement, it is not correct. return is a built-in keyword and not a function, so the patens are not needed. It is standard practice not to include the parens.

Post back if you need more help. Good luck!!!
