I can't pass Test Case 3 in Code Project – Phone Number Validator

Question

Hello everyone, I need a help.

In the block Regular Expressions I can not pass internal Test Case 3.

Task:
Phone Number Validator
You are given a number input, and need to check if it is a valid phone number.
A valid phone number has exactly 8 digits and starts with 1, 8 or 9.
Output "Valid" if the number is valid and "Invalid", if it is not.

Sample Input
81239870

Sample Output
Valid

My code:
import re
#this is my code
tel_number = input()
pattern = r"[189]\d{7}"

if re.match(pattern, tel_number):
print('Valid')
else:
print('Invalid')

Answer 1

Lyapunov Alexander ,

you have been very close, only '#x27; was missing at the end of the pattern:

pattern = r"[189]\d{7}" # your pattern
pattern = r"[189]\d{7}quot; # correct pattern

Answer 2

Ok, thank you very much. It's very useful.

Answer 3

Yes, I used pattern = r'^[189]\d{7}#x27; and it correctly.
