passed as the parameter only contains alphanumerical characters or is empty, otherwise, and returns false
.
Expected function

Here is a possible program to test your function :
package main

"piscine"
)
func main() {
fmt.Println(piscine.IsAlpha("Hello! How are you?"))
fmt.Println(piscine.IsAlpha("HelloHowareyou"))
