How to Split Strings and Assign Variables in Go?

Splitting Strings and Assigning Variables in Go

Unlike Python, which allows for simultaneous string splitting and variable assignment, Go requires a slightly different approach.

Two-Step Split

One method is to split the string into a slice and then assign the values:

package main

import (
    "fmt"
    "strings"
)

func main() {
    s := strings.Split("127.0.0.1:5432", ":")
    ip, port := s[0], s[1]
    fmt.Println(ip, port)
}

One-Step Split

Go's net package provides a convenient SplitHostPort function for splitting a host-port string directly into variables:

package main

import (
    "fmt"
    "net"
)

func main() {
    host, port, err := net.SplitHostPort("127.0.0.1:5432")
    fmt.Println(host, port, err)
}

Both approaches effectively allow you to split a string and assign the resulting values to variables in Go.
