在Go语言中, 弦与其他语言(例如Java, C ++, python等等。它是一系列可变宽度字符, 其中每个字符都使用UTF-8编码由一个或多个字节表示。在Go字符串中, 可以使用以下功能将字符串拆分为一个切片。这些函数是在字符串包下定义的, 因此, 你必须在程序中导入字符串包才能访问这些功能:
1.拆分:此函数将字符串拆分为由给定分隔符分隔的所有子字符串, 并返回包含这些子字符串的切片。
语法如下:
func Split(str, sep string) []string
这里, str是字符串, sep是分隔符。如果str不包含给定九月和九月为非空, 则它将返回长度为1的切片, 其中仅包含str。或者, 如果九月为空, 则它将在每个UTF-8序列之后拆分。或者如果两者都str和九月为空, 则将返回一个空切片。
例子:
//Go program to illustrate how to split a string
package main
import (
"fmt"
"strings"
)
//Main function
func main() {
//Creating and initializing the strings
str1 := "Welcome, to the, online portal, of srcmini"
str2 := "My dog name is Dollar"
str3 := "I like to play Ludo"
//Displaying strings
fmt.Println( "String 1: " , str1)
fmt.Println( "String 2: " , str2)
fmt.Println( "String 3: " , str3)
//Splitting the given strings
//Using Split() function
res1 := strings.Split(str1, ", " )
res2 := strings.Split(str2, "" )
res3 := strings.Split(str3, "!" )
res4 := strings.Split( "" , "srcmini, geeks" )
//Displaying the result
fmt.Println( "\nResult 1: " , res1)
fmt.Println( "Result 2: " , res2)
fmt.Println( "Result 3: " , res3)
fmt.Println( "Result 4: " , res4)
}
输出如下:
String 1: Welcome, to the, online portal, of srcmini
String 2: My dog name is Dollar
String 3: I like to play Ludo
Result 1: [Welcome to the online portal of srcmini]
Result 2: [M y d o g n a m e i s N a w a b]
Result 3: [I like to play Ludo]
Result 4: []
2. SplitAfter:此函数在给定分隔符的每个实例之后将字符串拆分为所有子字符串, 并返回包含这些子字符串的切片。
语法如下:
func SplitAfter(str, sep string) []string
这里, str是字符串, sep是分隔符。如果str不包含给定九月和九月为非空, 则它将返回长度为1的切片, 其中仅包含str。或者, 如果九月为空, 则它将在每个UTF-8序列之后拆分。或者如果两者都str和九月为空, 则将返回一个空切片。
例子:
//Go program to illustrate how to split a string
package main
import (
"fmt"
"strings"
)
//Main function
func main() {
//Creating and initializing the strings
str1 := "Welcome, to the, online portal, of srcmini"
str2 := "My dog name is Dollar"
str3 := "I like to play Ludo"
//Displaying strings
fmt.Println( "String 1: " , str1)
fmt.Println( "String 2: " , str2)
fmt.Println( "String 3: " , str3)
//Splitting the given strings
//Using SplitAfter() function
res1 := strings.SplitAfter(str1, ", " )
res2 := strings.SplitAfter(str2, "" )
res3 := strings.SplitAfter(str3, "!" )
res4 := strings.SplitAfter( "" , "srcmini, geeks" )
//Displaying the result
fmt.Println( "\nResult 1: " , res1)
fmt.Println( "Result 2: " , res2)
fmt.Println( "Result 3: " , res3)
fmt.Println( "Result 4: " , res4)
}
输出如下:
String 1: Welcome, to the, online portal, of srcmini
String 2: My dog name is Dollar
String 3: I like to play Ludo
Result 1: [Welcome, to the, online portal, of srcmini]
Result 2: [M y d o g n a m e i s N a w a b]
Result 3: [I like to play Ludo]
Result 4: []
3. SplitAfterN:此函数在给定分隔符的每个实例之后将字符串拆分为所有子字符串, 并返回包含这些子字符串的切片。
语法如下:
func SplitAfterN(str, sep string, m int) []string
这里, str是字符串, 九月是分隔符, m用于查找要返回的子字符串的数量。在这里, 如果m> 0, 那么最多返回米子字符串和最后一个字符串子字符串将不会拆分。如果m == 0, 则它将返回nil。如果m <0, 那么它将返回所有子字符串。
例子:
//Go program to illustrate how to split a string
package main
import (
"fmt"
"strings"
)
//Main function
func main() {
//Creating and initializing the strings
str1 := "Welcome, to the, online portal, of srcmini"
str2 := "My dog name is Dollar"
str3 := "I like to play Ludo"
//Displaying strings
fmt.Println( "String 1: " , str1)
fmt.Println( "String 2: " , str2)
fmt.Println( "String 3: " , str3)
//Splitting the given strings
//Using SplitAfterN() function
res1 := strings.SplitAfterN(str1, ", " , 2)
res2 := strings.SplitAfterN(str2, "" , 4)
res3 := strings.SplitAfterN(str3, "!" , 1)
res4 := strings.SplitAfterN( "" , "srcmini, geeks" , 3)
//Displaying the result
fmt.Println( "\nResult 1: " , res1)
fmt.Println( "Result 2: " , res2)
fmt.Println( "Result 3: " , res3)
fmt.Println( "Result 4: " , res4)
}
输出如下:
String 1: Welcome, to the, online portal, of srcmini
String 2: My dog name is Dollar
String 3: I like to play Ludo
Result 1: [Welcome, to the, online portal, of srcmini]
Result 2: [M y dog name is Dollar]
Result 3: [I like to play Ludo]
Result 4: []
