Trim()

The Trim() function removes leading and trailing characters from a string based on the given input. The strings library must be imported in order to use this function.

Syntax

trimmed := strings.Trim(str, cutset)

Where:

• str: The input string from which the leading and trailing characters are to be removed.
• cutset: The string containing the characters to be removed.
• trimmed: The resulting string after trimming.

Example

The following removes leading and trailing whitespace characters from a string and prints the result:

package main

import (
  "fmt"
  "strings"
)

func main() {
  str := "   Hello, World!   "
  trimmed := strings.Trim(str, " ")
  fmt.Println(trimmed)
}

The output will be:

Hello, World!
