Golang: How to pad a number with zeros when printing?
...
The fmt package can do this for you:
fmt.Printf("|%06d|%6d|\n", 12, 345)
Notice the 0 in %06d, that will make it a width of 6 and pad it with zeros. The second one will pad with spaces.
You can see it in action here: http://play.golang.org/p/cinDspMccp
