How to check a string for special characters?

Question

go

It is necessary to check the string for the presence of special characters and numbers. Check if the string contains only letters of the Latin alphabet.
For example, the string "roi134432-=-!"#;;" is not suitable, but the string "golang" is.
Python has a wonderful method that literally in a couple of lines of code does this check, do we have something magical?))) )

Answer 1

package main

import "fmt"
import "regexp"

var IsLetter = regexp.MustCompile(`^[a-zA-Z]+$`).MatchString

func main() {
    fmt.Println(IsLetter("golang")) // true
    fmt.Println(IsLetter("рои134432-=-!№;;")) // false
}
