Overview

A simple regex can be used to check if a string contains single or multiple white spaces in Go.

Here is the program for the same

Program

package main

import (
	"fmt"
	"regexp"
)

func main() {
	//Single whitespace
	sampleWord := "Good morning"

	isWhitespacePresent := regexp.MustCompile(`\s`).MatchString(sampleWord)
	fmt.Println(isWhitespacePresent)

	//Multiple Whitespace
	sampleWord = "Good   morning"
	isMultipleWhitespacePresent := regexp.MustCompile(`\s*`).MatchString(sampleWord)
	fmt.Println(isMultipleWhitespacePresent)
}

Output

true
true
