Go 自学：切片slices

以下代码展示了两种建立slice的方法。

我们可以使用sort函数给slice排序。

go 复制代码

package main

import (
	"fmt"
	"sort"
)

func main() {

	var fruitList = []string{"Apple", "Tomato", "Peach"}
	fmt.Printf("Type of fruitlist is %T\n", fruitList)

	fruitList = append(fruitList, "Mango", "Banana")
	fmt.Println(fruitList)

	fruitList = append(fruitList[:3])
	fmt.Println(fruitList)

	highScores := make([]int, 4)
	highScores[0] = 234
	highScores[1] = 945
	highScores[2] = 465
	highScores[3] = 867

	highScores = append(highScores, 555, 666, 321)

	fmt.Println(highScores)

	fmt.Println(sort.IntsAreSorted(highScores))
	sort.Ints(highScores)
	fmt.Println((highScores))
}

输出为：

Type of fruitlist is []string

[Apple Tomato Peach Mango Banana]

[Apple Tomato Peach]

[234 945 465 867 555 666 321]

false

[234 321 465 555 666 867 945]

以下代码展示了如何根据index从slice中移除指定元素。

go 复制代码

package main

import (
	"fmt"
)

func main() {

	var courses = []string{"reactjs", "javascript", "swift", "python", "ruby"}
	fmt.Println(courses)
	var index int = 2
	courses = append(courses[:index], courses[index+1:]...)
	fmt.Println(courses)
}
