WebOct 23, 2013 · The most obvious is to loop over its contents and pull out the bytes individually, as in this for loop: for i := 0; i < len (sample); i++ { fmt.Printf ("%x ", sample [i]) } As implied up front, indexing a string accesses individual bytes, not characters. We’ll return to that topic in detail below. For now, let’s stick with just the bytes.
