In this tutorial, we will learn how to get the last n characters of a given string in Golang.
In Golang, strings are the character sequence of bytes.
To access the last n characters of a string, we can use the slice expression
 in Go.
Here is an example, that gets the last 3 characters from the following string:
country := "France" lastThree:= country[len(country)-3:] fmt.Println(lastThree)
In the example above, we have passed
[len(country)-3:] to the slice expression. so it starts the extraction at position
len(country)-3 and extract the rest of a string.
