Validating phone numbers in python using RE

I'm trying to validate a phone number using Regex, using the below syntax. The number must start with 9 and has 9 digits after that. Can you please advice what can probably be wrong in this code.

import re
phn = "9123456789"

res = re.findall("(9)?[0-9]{9}", phn)

print (res)

O/p:
['9']

It is possible to use python library phonenumbers to validate the phone number extracted by commonregex :

import import commonregex
import phonenumbers

phone_list = commonregex.phone.findall(input_string)
for phone in phone_list:
    phonenumbers.is_valid_number(phonenumbers.parse(phone, None))

I hope it helps you.

? means "optionally." If your number must start with 9, you do not need ?:

re.findall("9[0-9]{9}", phn)

Or, better:

re.findall(r"9\d{9}", phn)
