In this shot, we will learn how to extract a substring from a string using Golang.
##
### Syntax

```
string[starting_index : ending_index]
```

> Note: `starting_index` is inclusive and the `ending_index` is exclusive, while extracting the substring.
##
### Return value

It returns a new string.

### Example
In the following example, we use the string `educative` and extract a substring from index `2` to the `end` of the string.

The end of the string is calculated by using the length of the string.

package main

//import the packages
import(
  "fmt"
)

//program execution starts from here
func main() {

  //declare and initialize the string
  str := "educative"

  // Take substring from index 2 to length of string
  substr := str[2:len(str)]

  //display the extracted substring
  fmt.Println(substr)

}

### Code explanation
In the code snippet above:

* Line 5: We import the `fmt` package, which is useful for printing the input and output.

* Line 9: The program execution starts from the `main()` function in Golang.

* Line 12: We declare and initialize the string `str`.

* Line 15: We extract the substring from the string `str` from index `2` to the end of the string (`len(str)`).

* Line 18: We display the extracted substring `substr`.
