String manipulation functions are a must have for a programming language and Go has plenty of them. In this tutorial we will see how to trim white spaces of a string in Go

To trim white spaces from a string

 str := "  This is a string with white spaces\n "
 fmt.Printf("%d %q\n", len(str), str)

 trimmed := strings.TrimSpace(str)
 fmt.Printf("%d %q\n", len(trimmed), trimmed)

output :

38 " This is a string with white spaces\n "

34 "This is a string with white spaces"

 import (
 "fmt"
 "strings"
 )

 func main() {
 str := "  This is a string with white spaces\n "

 fmt.Printf("%d %q\n", len(trimmed), trimmed)
 }
