How do I trim whitespace from a string in Go?

How do I trim whitespace from a string in Go?

You can use the strings.TrimSpace function from the strings package to remove leading and trailing whitespace.

Can you show me an example of how to use it?

Sure! Here's a simple example:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "   Hello, World!   "
    trimmedStr := strings.TrimSpace(str)
    fmt.Println(trimmedStr) // Output: "Hello, World!"
}

What if I want to trim specific characters instead of whitespace?

You can use strings.Trim to remove specific characters. For example:

trimmedStr := strings.Trim(str, " ") // Trims spaces
trimmedStr := strings.Trim(str, "! ") // Trims spaces and exclamation marks
