This article will provide methods to divide strings in Go.

Split a String With Delimiters Using the Split() Method in Go

In Go, the Split() function (included in the strings package) divides a string into a list of substrings using a separator. The substrings are returned in the form of a slice.

In the following example, we’ll use a string with values separated by commas as delimiters.

Example 1:

package main

import (
    "fmt"
    "strings"
)

func main() {
    var str = "a-b-c"
    var delimiter = "-"
    var parts = strings.Split(str, delimiter)
    fmt.Println(parts)
}

Output:

[a b c]

Example 2:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "hi, there!, Good morning"
    split := strings.Split(str, ",")
    fmt.Println(split)
    fmt.Println("Length of the slice:", len(split))
}

Output:

[hi  there!  Good morning]
Length of the slice: 3

Example 3:

package main

import (
    "fmt"
    "strings"
)

func main() {
    carString := "BMW,GMC,Supra,Audi"
    cars := strings.Split(carString, ",")
    fmt.Println(cars)
}

Output:

[BMW GMC Supra Audi]

Split a String With Delimiters Using the SplitAfter() Method in Go

SplitAfter() separates the original text but leaves the delimiters at the end of each substring, similar to Split().

package main

import (
    "fmt"
    "strings"
)

func main() {
    carString := "BMW.GMC.Supra.Audi"
    cars := strings.SplitAfter(carString, ".")
    fmt.Println(cars)
}

Output:

[BMW. GMC. Supra. Audi]
