Split() FUNCTION

Split() Function

The Split() Function is used to split a string based on the value provided.

Example :

package main
import "fmt"
import "strings"
    
func main() {
    
    x := "Hello Beautiful World"
    var arr []string = strings.Split(x, " ") 
            
    for i, v := range arr {  
        fmt.Println("arr[",i,"] =", v)  
    } 
}

Output :

arr[ 0 ] = Hello
arr[ 1 ] = Beautiful
arr[ 2 ] = World

So, in the above code, we have a String 'Hello Beautiful World' initialised to a variable 'x'.

Then we have used the 'split()' function on the variable 'x'.

var arr []string = strings.Split(x, " ")

So, the 'Split()' function converts the String, 'Hello Beautiful World' to an Array, separated by a space (i.e. ' ').

And initialises the array to the variable 'arr'.

So, if you see the above String, 'Hello Beautiful World'. 'Hello', 'Beautiful' and 'World' are separated by a space (i.e. ' ').

So, an array is formed with 'Hello', 'Beautiful' and 'World'.

But what if the Strings are separated by '@' or any other symbol.

Say, the below String is separated by '@'.

"Hello@Beautiful@World"

Now, if you want to form an array with 'Hello', 'Beautiful' and 'World'. You can use 'Split()' function providing the separator '@' as argument.

'Split()' Function using separator as an argument

Example :

import "fmt"
import "strings"
    
func main() {
    
    x := "Hello@Beautiful@World"
    var arr []string = strings.Split(x, "@") 
            
    for i, v := range arr {  
        fmt.Println("arr[",i,"] =", v)  
    } 
}

Output :

arr[ 0 ] = Hello
arr[ 1 ] = Beautiful
arr[ 2 ] = World

So, in the above code, we have a String 'Hello@Beautiful@World' initialised to a variable 'x'.

Then we have used the 'split()' function with the separator '@' as argument on the variable 'x'.

var arr []string = strings.Split(x, "@")

So, the 'Split()' function converts the String, 'Hello@Beautiful@World' to an Array, separated by the separator (i.e. '@').

And initialises the Array to the variable 'arr'.
