在Go语言中,没有像Python中的in操作符,但是可以通过使用for循环遍历数组、切片、映射、通道等数据结构,判断是否包含某个元素。例如,可以使用以下代码判断一个切片中是否包含某个字符串: func contains(slice []string, str string) bool { for _, s := range slice { if s == str { return true } } ret...
In this program, we will create a slice from an array of integers and then iterate the slice elements using the range in the "for" loop and print on the console screen. Program/Source Code: The source code toiterate a slice using the range in the "for" loopis given below. The given...
