Go Multi-case switch Statement
The Multi-case switch Statement
It is possible to have multiple values for each case in the switch 
statement:
Syntax
        switch expression { 
        case x,y: 
 
           // code block if expression is evaluated to x or y  
        case v,w: 
 
           // code block if expression is evaluated to v or w  
        case z: 
        ... 
        default: 
           // code block if expression is not found in any cases  
 
        }    
      
Multi-case switch Example
The example below uses the weekday number to return different text:
Example
    package main
    import ("fmt")
    
    func main() { 
         day := 5 
         switch day {
         case 1,3,5:
          fmt.Println("Odd weekday")
         case 2,4:
           fmt.Println("Even weekday")
         case 6,7:
          fmt.Println("Weekend")
        default:
          fmt.Println("Invalid day of day number")
        }
    }
    
  Result:
Odd weekday
