How to get the last n characters of a string in Golang

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.

Getting the last n characters

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)

Output:

nce

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.
