switch 1: 在条件语句中,可以写多条的语句
2: 也可以不添加语句
package main import ( "fmt" "time" ) func main() { i := 2 fmt.Println("write ", i, " as ") switch i { case 1: fmt.Println("one") case 2: fmt.Println("two") case 3: fmt.Println("three") } switch time.Now().Weekday() { case time.Saturday, time.Sunday: fmt.Println("it's the weekend") default: fmt.Println("it's a weekday") } t := time.Now() switch { case t.Hour() < 12: fmt.Println("it's before noon") default: fmt.Println("it's after noon") } }
write 2 as two it's a weekday it's after noon
