fmt.Println code example

Example 1: go format string

s := fmt.Sprintf("string: %s number: %d time: %v", "string", 1, time.Now())

Example 2: print in golang

package Main
//you need to import fmt
import ("fmt")

func main(){
	//then you can use:
	fmt.Print("this message will be printed without a linefeed at the end")
	//or
	fmt.Println("this message will be printed with a linefeed a the end")
	//or										   the \n is a line feed
 	fmt.Printf("You can also use %s formatings with Printf \n (PS : this message won't end with a line feed)","multiples")
  	// will output :
  	/*You can also use multiples formatings with Printf 
      (PS : this message won't end with a line feed)*/
}
// More infos at https://golang.org/pkg/fmt/ or in the source

Example 3: format string go

fmt.Sprintf("foo: %s", bar)

Example 4: %+v in golang

%v	the value in a default format
	when printing structs, the plus flag (%+v) adds field names
%#v	a Go-syntax representation of the value
%T	a Go-syntax representation of the type of the value
%%	a literal percent sign; consumes no value

Example 5: format string go
