How Can I Print Multiple Return Values from a Go Function Using fmt.Printf()?

Passing Multiple Return Values to Variadic Functions

In Go, a function can return multiple values. However, directly assigning the return values of a function to a format string in a call to fmt.Println() is not possible by default.

Approach Using fmt.Printf()

To achieve the desired behavior, fmt.Printf() should be used instead of fmt.Println(). However, passing additional parameters besides the function call is not allowed by the specification for variadic function calls.

Using a Wrapper Function

To bypass this restriction, a wrapper function can be employed. The wrap() function takes multiple values and returns them as a slice of interface{} values. This allows us to pass the return values of any function with at least one return value to fmt.Printf().

Conclusion

By using the wrap() function, it is possible to pass multiple return values of a function to a variadic function like fmt.Printf(). This provides a simple and convenient way to format and print the results of a function call.
