Unpack slices on assignment?

Question

Is there an elegant way in Go to do multiple assignments from arrays like in Python? Here is a Python example of what I\'m trying to do (split a string and then assign the r

If your function is meant to split a string only by the first occurrence of the separator, you can always make your own function:

package main

import (
    "fmt"
    "strings"
)

func Split(s, sep string) (string, string) {
    // Empty string should just return empty
    if len(s) == 0 {
        return s, s
    }   

    slice := strings.SplitN(s, sep, 2)

    // Incase no separator was present
    if len(slice) == 1 {
        return slice[0], ""
    }

    return slice[0], slice[1]
}

func main() {
    a, b := Split("foo;bar;foo", ";")
    fmt.Println(a, b)
}

Output:

foo bar;foo
