How to solve “too many arguments to return” issue in Golang?

Question

In a print function I am writing, I am trying to return a value based on the result of a switch statement; however, I am getting the error too many arguments to return.

Answer 1

You need to specify what you will return after specifying the input parameters, this is not python.

This:

func Print(DATA []TD, include string, exclude []string, str string) {

Should be:

func Print(DATA []TD, include string, exclude []string, str string) string {
