Go: Retrieve a string from between two characters or other strings

Question

Let\'s say for example that I have one string, like this:

Hello World!

What Go code would be able to extract Hel

Answer 1

There are lots of ways to split strings in all programming languages.

Since I don't know what you are especially asking for I provide a sample way to get the output you want from your sample.

package main

import "strings"
import "fmt"

func main() {
    initial := "
Hello World!
"

    out := strings.TrimLeft(strings.TrimRight(initial,""),"
")
    fmt.Println(out)
}

In the above code you trim

from the left of the string and

from the right.

As I said there are hundreds of ways to split specific strings and this is only a sample to get you started.

Hope it helps, Good luck with Golang :)
