How to split a string and assign it to variables

Question

In Python it is possible to split a string and assign it to variables:

ip, port = \'127.0.0.1:5432\'.split(\':\')

but in Go it does not see

Answer 1

Since go is flexible an you can create your own python style split ...

package main

import (
    "fmt"
    "strings"
    "errors"
)

type PyString string

func main() {
    var py PyString
    py = "127.0.0.1:5432"
    ip, port , err := py.Split(":")       // Python Style
    fmt.Println(ip, port, err)
}

func (py PyString) Split(str string) ( string, string , error ) {
    s := strings.Split(string(py), str)
    if len(s) < 2 {
        return "" , "", errors.New("Minimum match not found")
    }
    return s[0] , s[1] , nil
}
