Python phone validator

Question

I can’t get past this challenge in the Python learning path.
A valid phone begins with 1,8,9 and is 8 characters long. I used this regex in an online editor and this works but I’m not sure why Python code isn’t accepting this for the tests?
import re
#your code goes here
pa = r"^[189][0-9]{7}

Answer 1

is it there not required to take input?
str = input()

Answer 2

thanks for the reply. I assigned the str to input() and that allowed me to pass. thanks!!!!

Answer 3

You're welcome..
