法律研究Golang – strings.SplitN()
strings.SplitN() 是 Go 语言中用于通过给定分隔符对给定字符串拆分成子字符串的内置函数。它返回这些分隔符之间的子字符串的切片。
语法
func SplitN(str, sep string, n int) []string
其中：
- str 是给定的输入字符串，
- sep 是分隔符字符串，
- n 定义要返回的子字符串数。
示例 1
考虑以下示例 −
package main
import (
"fmt"
"strings"
)
func main() {
// Intializing the Strings
p := "1, 2, 3, 4, 5, 6, 7"
q := "Welcome to Golang Programming Language"
r := "SplitN"
s := "1.2.3.4.5"
t := "String/Package/Function"
// Display the Strings
fmt.Println("String 1: ", p)
fmt.Println("String 2: ", q)
fmt.Println("String 3: ", r)
fmt.Println("String 4: ", s)
fmt.Println("String 5: ", t)
// Using the SplitN Function
test1 := strings.SplitN(p, ",", 6)
test2 := strings.SplitN(q, " ", 0)
test3 := strings.SplitN(r, "N", -1)
test4 := strings.SplitN(s, ".", 5)
test5 := strings.SplitN(t, "/", 3)
test6 := strings.SplitN(q, "to ", -1)
test7 := strings.SplitN(s, ".", 4)
// Display the SplitN Output
fmt.Println("\nSplitN for String 1:", test1)
fmt.Println("SplitN for String 2:", test2)
fmt.Println("SplitN for String 3:", test3)
fmt.Println("SplitN for String 4:", test4)
fmt.Println("SplitN for String 5:", test5)
fmt.Println("SplitN for String 2:", test6)
fmt.Println("SplitN for String 4:", test7)
}输出
它将生成以下输出 −
String 1: 1, 2, 3, 4, 5, 6, 7 String 2: Welcome to Golang Programming Language String 3: SplitN String 4: 1.2.3.4.5 String 5: String/Package/Function SplitN for String 1: [1 2 3 4 5 6, 7] SplitN for String 2: [] SplitN for String 3: [Split ] SplitN for String 4: [1 2 3 4 5] SplitN for String 5: [String Package Function] SplitN for String 2: [Welcome Golang Programming Language] SplitN for String 4: [1 2 3 4.5]
示例 2
我们再举一个例子。
package main
import (
"fmt"
"strings"
)
func main() {
// Declaring the Variables
var x string
var y string
// Intializing the Strings
x = "Golang Programming Language"
y = "SplitN-String-Package-Function"
// Display the Strings
fmt.Println("String 1: ", x)
fmt.Println("String 2:", y)
// Using SplitN
z := strings.SplitN(x, "Programming", 2)
w := strings.SplitN(y, "-", 3)
// Display the SplitN Output
fmt.Println("SplitN for String 1:", z)
// Using the for condition to display outputs of y variable
for v := range(w) {
fmt.Println("SplitN Function for String 2: ", w[v])
}
}输出
它将生成以下输出 −
String 1: Golang Programming Language String 2: SplitN-String-Package-Function SplitN for String 1: [Golang Language] SplitN Function for String 2: SplitN SplitN Function for String 2: String SplitN Function for String 2: Package-Function
