How to Trim a String in Golang?

In Go, strings are UTF-8 encoded sequences of variable-width characters, unlike some other languages like Java, python and C++. Go provides several functions within the strings package to trim characters from strings.In this article we will learn how to Trim a String in Golang.

Example

s := "@@Hello, Geeks!!"

Syntax

func Trim(s string, cutset string) string #Trim
func TrimLeft(s string, cutset string) string # TrimLeft
func TrimRight(s string, cutset string) string # TrimRight
func TrimSpace(s string) string # TrimSpace
func TrimPrefix(s, prefix string) string # TrimPrefix
func TrimSuffix(s, suffix string) string # TrimSuffix 

Trim

The Trim function removes all specified leading and trailing characters from a string.

Syntax

func Trim(s string, cutset string) string

• s: The string to trim.
• cutset: Characters to remove from both ends.

Example:

package main  import (  "fmt"  "strings" ) func main() {  s := "@@Hello, Geeks!!"  result := strings.Trim(s, "@!")  fmt.Println(result) } 

Hello, Geeks 

TrimLeft

The TrimLeft function removes specified characters from the start of a string.

Syntax

func TrimLeft(s string, cutset string) string

Example:

package main import (  "fmt"  "strings" ) func main() {  s := "@@Hello, Geeks!!"  result := strings.TrimLeft(s, "@!")  fmt.Println(result) } 

Hello, Geeks!! 

TrimRight

The TrimRight function removes specified characters from the end of a string.

Syntax

func TrimRight(s string, cutset string) string

Example

package main import (  "fmt"  "strings" ) func main() {  s := "@@Hello, Geeks"  result := strings.TrimRight(s, "Geeks")  fmt.Println(result) } 

@@Hello, 

TrimSpace

The TrimSpace function removes all leading and trailing whitespace from a string.

Syntax

func TrimSpace(s string) string

Example:

package main import (  "fmt"  "strings" ) func main() {  s := " Hello, Geeks "  result := strings.TrimSpace(s)  fmt.Println(result) } 

Hello, Geeks 

TrimPrefix

The TrimPrefix function removes a specified prefix from the beginning of a string if present.

Syntax

func TrimPrefix(s, prefix string) string

Example:

package main import (  "fmt"  "strings" ) func main() {  s := "@@Hello, Geeks!!"  result := strings.TrimPrefix(s, "@@")  fmt.Println(result) } 

Hello, Geeks!! 

TrimSuffix

The TrimSuffix function removes a specified suffix from the end of a string if present.

Syntax

package main import (  "fmt"  "strings" ) func main() {  s := "@@Hello, Geeks"  result := strings.TrimSuffix(s, "eeks")  fmt.Println(result) }
