Golang : How to detect if a sentence ends with a punctuation?


Tags : golang natural-language-processing punctuation-mark convert-string-to-rune

Problem : I need to detect if a line ends with a punctuation mark or not. How to do that?

Solution : In Golang, a string is also a slice, get the last character out from the sentence, convert the string to rune and use unicode.IsPunct() function to check if the last character is a punctuation or not.

Here you go!


 package main

 import (
  "log"
  "unicode"
 )

 func main() {
  //str := "this is a line with fullstop."
  str := "this is a line with without fullstop"
  

  lastChar := str[len(str)-1:]
  lastCharRune := []rune(lastChar)
  if unicode.IsPunct(lastCharRune[0]) { // this is how to convert string to rune ;-)
 log.Println("lastChar is a punctuation :", lastChar)
  } else {
 log.Println("lastChar is not a punctuation :", lastChar)
  }
 }

Happy coding!
