Go Cut()

The Cut() function slices a string around a separator. The strings library must be imported in order to use this function.

Syntax

before, after, found := strings.Cut(s, sep)

Where before is the part of the string before the separator, after is the part of the string after the separator, and found is a boolean indicating whether the separator was found in the string.

Example

The following example removes the substring world from the original string Hello, world! and prints out the result:

package main

import (
  "fmt"
  "strings"
)

func main() {
  s := "Hello, world!"
  sep := ","
  before, after, found := strings.Cut(s, sep)
  fmt.Printf("Cut(%q, %q) = %q, %q, %v\n", s, sep, before, after, found)
}
