Go Language String Splitting

In the Go language,stringDifferent from Java, C ++, Python, and other languages. It is a series of variable-width characters, where each character is represented by UTF-8Encoding is represented by one or more bytes. In Go strings, you can use the following functions to split a string into a slice. These functions are defined under the string package, so you must import the string package in your program to access these functions:

1.Split:This function splits a string into all substrings separated by the given delimiter and returns a slice containing these substrings.

Syntax:

func Split(str, sep string) []string

Here, str is a string, sep is the delimiter. If str does not contain the given sep and sep is not empty, it will return a slice of length1slice containing only str. Or, if sep is empty, it will split at each UTF-8to split the sequence. Or, if both str and sep are empty, it will return an empty slice.

package main
import (
　　　　"fmt"
　　　　"strings"
)
func main() {
　　　　//Create and initialize strings
　　　　str1　:= "Welcome, to the, online portal, of w3codebox"
　　　　str2　:= "My dog name is Dollar"
　　　　str3　:= "I like to play Ludo"
　　　　//Display string
　　　　fmt.Println("String　1: "str1)
　　　　fmt.Println("String　2: "str2)
　　　　fmt.Println("String　3: "str3)
　　　　//Split the given string
　　　　//Using the Split() function
　　　　res1　:= strings.Split(str1, ",")
　　　　res2　:= strings.Split(str2, "")
　　　　res3　:= strings.Split(str3, "!")
　　　　res4　:= strings.Split("", "w3codebox, geeks"
　　　　//　Display result
　　　　fmt.Println("\nResult　1: "res1)
　　　　fmt.Println("Result　2: "res2)
　　　　fmt.Println("Result　3: "res3)
　　　　fmt.Println("Result　4: "res4)
　　　}

Output:

String　1: Welcome, to the, online portal, of w3codebox
String　2: My dog name is Dollar
String　3: I like to play Ludo
Result　1: [Welcome to the online portal of w3codebox]
Result　2: "My dog name is Dollar"
Result　3: I like to play Ludo
Result　4:　　[]

2. SplitAfter:This function splits the string after each instance of the given separator into all substrings and returns a slice containing these substrings.

Syntax:

func SplitAfter(str, sep string) []string

Here, str is a string, sep is the delimiter. If str does not contain the given sep and sep is not empty, it will return a slice of length1slice containing only str. Or, if sep is empty, it will split at each UTF-8to split the sequence. Or, if both str and sep are empty, it will return an empty slice.

package main
import (
　　　　"fmt"
　　　　"strings"
)
func main() {
　　　　//Create and initialize strings
　　　　str1　:= "Welcome, to the, online portal, of w3codebox"
　　　　str2　:= "My dog name is Dollar"
　　　　str3　:= "I like to play Ludo"
　　　　//Display string
　　　　fmt.Println("String　1: "str1)
　　　　fmt.Println("String　2: "str2)
　　　　fmt.Println("String　3: "str3)
　　　　//Split the given string
　　　　//Using the SplitAfter() function
　　　　res1　:= strings.SplitAfter(str1, ",")
　　　　res2　:= strings.SplitAfter(str2, "")
　　　　res3　:= strings.SplitAfter(str3, "!")
　　　　res4　:= strings.SplitAfter("", "w3codebox, geeks"
　　　　//Display result
　　　　fmt.Println("\nResult　1: "res1)
　　　　fmt.Println("Result　2: "res2)
　　　　fmt.Println("Result　3: "res3)
　　　　fmt.Println("Result　4: "res4)
}

Output:

String　1: Welcome, to the, online portal, of w3codebox
String　2: My dog name is Dollar
String　3: I like to play Ludo
Result　1: "Welcome, to the, online portal, of w"3codebox]
Result　2: "My dog name is Dollar"
Result　3: I like to play Ludo

3. SplitAfterN:This function splits the string after each instance of the given separator into all substrings and returns a slice containing these substrings.

Syntax:

func SplitAfterN(str, sep string, m int) []string

here,stris a string,sepis the separator, m is used to find the number of substrings to return. Here, ifm > 0then it will return at mostmsubstrings, and the last string substring will not be split. Ifm == 0it will return nil. Ifm < 0If m is greater than the number of substrings, it will return all substrings.

package main　
　　
import (　
　　　　"fmt"
　　　　"strings"
)　
　　
func main() {　
　　
　　　　//Create and initialize strings
　　　　str1　:= "Welcome, to the, online portal, of w3codebox"
　　　　str2　:= "My dog name is Dollar"
　　　　str3　:= "I like to play Ludo"
　　
　　　　//Display string
　　　　fmt.Println("String　1: "str1)　
　　　　fmt.Println("String　2: "str2)　
　　　　fmt.Println("String　3: "str3)　
　　
　　　　//Split the given string
　　　　//Use SplitAfterN() function
　　　　res1　:= strings.SplitAfterN(str1, ",",　2)　
　　　　res2　:= strings.SplitAfterN(str2, "",　4)　
　　　　res3　:= strings.SplitAfterN(str3, "!",　1)　
　　　　res4　:= strings.SplitAfterN("", "w3codebox, geeks　3)　
　　
　　　　//Display result　
　　　　fmt.Println("\nResult　1: "res1)　
　　　　fmt.Println("Result　2: "res2)　
　　　　fmt.Println("Result　3: "res3)　
　　　　fmt.Println("Result　4: "res4)　
　　
}

Output:

String　1: Welcome, to the, online portal, of w3codebox
String　2: My dog name is Dollar
String　3: I like to play Ludo
Result　1: Welcome, to the, online portal, of w3codebox]
Result　2: My dog name is Dollar
Result　3: I like to play Ludo
Result　4:　　[]
