How to Split a String on Whitespace in Go

by

To split a string on whitespace characters (spaces, tabs, and newlines) in Go, you can use the strings.Fields() function from the strings package. 

package main

import (
  "fmt"
  "strings"
)

func main() {
  input := "This is John Wick"

  words := strings.Fields(input)

  fmt.Println("Words in the input string:")
  for i, word := range words {
    fmt.Printf("Word %d: %s\n", i+1, word)
  }
}

Output

Words in the input string:
Word 1: This
Word 2: is
Word 3: John
Word 4: Wick

In this code example, we used strings.Fields() function to split the input string on whitespace characters.

The words variable will hold a slice of strings containing the individual words from the input string.

The strings.Fields() function splits the input string based on any whitespace character, including spaces, tabs, and newlines.

That’s it.
