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

    "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)
}

TrimSpace

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

Syntax

Example:

package main
import (
    "fmt"

    s := "   Hello, Geeks   "
    result := strings.TrimSpace(s)
    fmt.Println(result)
}

TrimPrefix

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

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