How to Split a String by Space in Go Language

Example 1: Using Split() Method

The Split() method​ in Go defined in the strings library splits a string down into a list of substrings using a specified separator. The method returns the substrings in the form of a slice.

package main
import (
    "fmt"
    "strings"
)
func main() {
    str := "Go C C++ Python Java Kotlin Php JS"
    //split string using Split() method
    out := strings.Split(str, " ")
    for j := 0; j < len(out); j++ {
        fmt.Println(out[j])
    }
}

Output:

Example 2: Using Fields() Method

The Fields() method in the strings package separates these into an array. It splits into groups of spaces.

package main
import (
    "fmt"
    "strings"
)
func main() {
    str := "Go C C++ Python Java Kotlin Php JS"
    //split string using Fields() method
    out := strings.Fields(str)
    for j := 0; j < len(out); j++ {
        fmt.Println(out[j])
    }
}

Output:

Example 3: Using Regular expressions

Regular expressions can be used to split the string using the pattern of the delimiters

package main
import (
    "fmt"
    "regexp"
)
func main() {
    str := "Go C C++ Python Java Kotlin Php JS"
    //split string using regexp
    regx := regexp.MustCompile(`[ ]`)
    //arg -1 means no limits for the number of substrings
    out := regx.Split(str, -1)
    for j := 0; j < len(out); j++ {
        fmt.Println(out[j])
    }
}

Output:
