Go by Example: Switch

Switch statements express conditionals across many branches.
	package main
	import "fmt" import "time"
	func main() {
Here’s a basic `switch`.	i := 2 fmt.Print("write ", i, " as ") switch i { case 1: fmt.Println("one") case 2: fmt.Println("two") case 3: fmt.Println("three") }
You can use commas to separate multiple expressions in the same `case` statement. We use the optional `default` case in this example as well.	switch time.Now().Weekday() { case time.Saturday, time.Sunday: fmt.Println("it's the weekend") default: fmt.Println("it's a weekday") }
`switch` without an expression is an alternate way to express if/else logic. Here we also show how the `case` expressions can be non-constants.	t := time.Now() switch { case t.Hour() < 12: fmt.Println("it's before noon") default: fmt.Println("it's after noon") } }

$ go run switch.go 
write 2 as two
it's the weekend
it's before noon
