如何在切片中写入函数的结果

Question

In the example, everything works fine. But they do not use the variable a and immediately display it https://play.golang.org/p/O0XwtQJRej

But I have a problem:

package main
import (
    "fmt"
    "strings"
)

func main() {
    str := "fulltext"
    var slice []string
    slice = strings.Split(str , "")

    fmt.Printf("anwer: ", slice)
}

Whence in the answer there are superfluous characters, for example

%! (EXTRA [] string =

P.S. I know that I need to use append to add elements to the slice, but now I do not understand how to apply append here.

UP: Now I have the answer:

anwer: %!(EXTRA []string=[f u l l t e x t])

But I need just:

[f u l l t e x t]

But I do not understand how I should change my code?

Answer 1

Give to printf the expected format, in most cases, %v is fine.

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "fulltext"
    var slice []string
    slice = strings.Split(str, "")

    fmt.Printf("anwer: %v", slice)
}

see https://golang.org/pkg/fmt/ for more info.
