# isprintable ## Instructions Write a function that returns `true` if the `string` passed in parameter only contains printable characters, and that returns `false` otherwise. ## Expected function ```go package main func IsPrintable(str string) bool { } ``` ## Usage Here is a possible [program](TODO-LINK) to test your function : ```go package main import ( "fmt" piscine ".." ) func main() { fmt.Println(piscine.IsPrintable("Hello")) fmt.Println(piscine.IsPrintable("Hello\n")) } ``` And its output : ```console student@ubuntu:~/piscine/test$ go build student@ubuntu:~/piscine/test$ ./test true false student@ubuntu:~/piscine/test$ ```
