Basics
require "fmt" fmt.Println("foo") // print to stdout with newline fmt.Printf("%v", 123) // print formatted string to stdout (no newline) fmt.Fprintf(os.Stdout, "%v", 123) // prints formatted string to writable object (ex. STDOUT, STERR, ..) fmt.Sprintf("%v", 123) // returns formatted string (no newline)Format Syntax
Printf/Sprintf/Fprintf all take format specifiers.
See full docs here, but here's some really useful formats:# general %v # value %T # type # number-bases %b # binary %x # hex %o # octal %d # decimal # number types %i # int %f # float # strings %s # string %q # quoted/escaped go string %c # unicode-char for num
